ALEPH-7; 2,5-DIMETHOXY-4-(n)-PROPYLTHIOAMPHETAMINE

SYNTHESIS: A solution of 2.6 g 2,5-dimethoxy-4-((n)-propylthio)benzaldehyde (see under 2C-T-7 for its synthesis) in 20 mL nitroethane and 0.5 g anhydrous ammonium acetate was heated on the steam bath overnight. The excess solvent/reagent was removed under vacuum leaving an orange oil as a residue that cry-stallized spontaneously. This crude product was recrystallized from 20 mL boiling MeOH to give, after cooling, filtering, and air drying, 2.4 g of 1-(2,5-dimethoxy-4-(n)-propylthiophenyl)-2-nitropropene as orange crystals. Its mp was 83-84 deg C with prior sintering at 81 deg C. A suspension of 1.5 g LAH in 150 mL of warm anhydrous THF was stirred under an inert atmosphere and brought up to a gentle reflux. A solution of 2.3 g 1-(2,5-dimethoxy-4-(n)-propylthiophenyl)-2-nitropropene in 25 mL anhydrous THF was added dropwise at a rate that maintained the reflux. Heating and stirring were continued for 2 days, and then the reaction mixture was allowed to stir at room temperature for an additional 2 days. There was added 1.5 mL H2O (dissolved in 10 mL THF), followed by 1.5 mL 15% NaOH, and finally another 4.5 mL H2O. Stirring was continued until all the curdy solids had turned white. The reaction mixture was filtered, and the filter cake washed with slightly wet THF. The filtrate and the washings were combined, and the solvent removed under vacuum. The residue was about 2 mL of an amber colored oil that was dissolved in 200 mL CH2Cl2. This solution was washed with first dilute NaOH, and then with saturated brine. Removal of the solvent gave a pale amber oil that was dissolved in 10 mL IPA, neutralized with about 14 drops of concentrated HCl, and diluted with 200 mL anhydrous Et2O. The clear solution was decanted from a little gritty material, and then set aside to allow the formation of 2,5-dimethoxy-4-(n)-propylthioamphetamine hydrochloride (ALEPH-7) as fine white crystals. After filtration and air drying, there was obtained 1.8 g of an off-white powder.

DOSAGE: 4 - 7 mg.

DURATION: 15 - 30 h.

QUALITATIVE COMMENTS: (with 4 mg) At the second hour I had a paraesthetic twinge or two (all pins and needles), and then felt quite relaxed, quite willing to let this play itself out. In the evening my ears still feel 'popped' and there is a little bit of physical awareness. There is not much fun with this. The night following, I was unable to sleep and only dozed slightly, but I seemed to be OK the next day.

(with 6 mg) The alert was felt within a half hour, and then nothing more. Then, over the next two hours, there was the evolution of an extremely neutral state. I danced wildly to a record of Keith Jarrett, but somehow didn't care for his style. I fell apart emotionally, with tears and a feeling of total loss of everything. Everything was visible to me only in some strange wide-angle lens viewing. I went for a walk, a waste of time. I tried classical music, but only jazz was acceptable. It was a couple of days before I lost the residual strangeness feeling. Never again.

(with 7 mg) I did this alone, and in retrospect I wish I had not. Somewhere between the hours 2 and 3, I got to a full +++, and I was concerned that I saw the effects still developing. Where would it go now? There was no reality loss as with LSD, no shakes or shimmers, but an intense and profound +++ of something characterized only by the absence of extremes. And I am frightened because this is still deepening. A couple of calls to friends were not successful, but I found an ally in the Palo Alto area, and I told him I was coming to visit. My greater than one hour drive there was okay only because I had programmed every move ahead of time. In retrospect, to drive was completely stupid, and I certainly will never do it again, under any circumstances. But, there I was. I knew which lane I would be on, on the S.F. Bay Bridge, at every moment of my travels. The middle lane through the tunnel. The second from the left when descending into San Francisco. The white lane-marker stripes were zipping up past my lateral field of vision as I drove, those that were to my right zipped past my right eye, those to the left past my left eye. Like disturbed fruit flies leaving an over-ripe peach. But, as everything had been preprogrammed, there were no surprises. I made it successfully, and my baby-sitting friend probed, with a blend of curiosity, love, and envy, my uncaring state. And in the course of the next couple of hours, this state evolved into a friendly, familiar place. I was still fully +++, but now for the first time I was at peace with it. A fruit salad tasted heavenly. By midnight I was able to doze lightly, and the next day I was sure that there were some residual effects. The second evening's sleep repaired everything. The neutralness was something new to me. I don't like not caring. Was this the "Beth" state of the strange twenty minutes seen by SL in the ALEPH-4 experience?

(with 7 mg) Strange, pleasant, unexciting, long-lasting. The induced state was characterized by: clear unintoxicated central field of vision, concentration but with the periphery sensed as being filled with a kind of strangeness, and also something sensed inside, at the back of the head. A feeling of something waiting to erupt, which never does. I had a faint touch of amusement, yet no part of the experience had the depth or richness of other compounds. No tremors. Slight visuals, but only when looked for. Hunger not present, but food tasted fine when eaten. Mildly pleasant but one would not take it again unless bored stiff.

EXTENSIONS AND COMMENTARY: This drug was the first definition of the term, Beth state.

There is something of the Fournier Transform in any and all drug experiments. A psychedelic drug experience is a complex combination of many signals going all at the same time. Something like the sound of an oboe playing the notes of the A-major scale. There are events that occur in sequence, such as the initial A, followed by B, followed by C-sharp and on and on. That is the chronology of the experience, and it can be written down as a series of perceived phenomena. The notes of the scale. Black quarter notes, with flags at the tops of their staffs, going up the page of music.

But within each of these single events, during the sounding of the note "A," for example, there is a complex combination of harmonics being produced at the same time, including all components from the fundamental oscillation on up through all harmonics into the inaudible. This mixture defines the played instrument as being an oboe. Each component may be shared by many instruments, but the particular combination is the unique signature of the oboe.

This analogy applies precisely to the study of psychedelic drugs and their actions. Each drug has a chronology of effect, like the notes of the A-major scale. But there are many components of a drug's action, like the harmonics from the fundamental to the inaudible which, taken in concert, defines the drug. With musical instruments, these components can be shown as sine waves on an oscilloscope. One component, 22%, was a sine wave at a frequency of 1205 cycles, and a phase angle of +55!. But in psychopharmacology? There is no psychic oscillo-scope. There are no easily defined and measured harmonics or phase angles. Certainly, any eventual definition of a drug will require some such dissection into components each of which makes some contribution to the complex whole. The mental process may some day be defined by a particular combination of these components. And one of them is this Beth state. It is a state of uncaring, of anhe-donia, and of emotionlessness.

Many drugs have a touch of this Beth state, ALEPH-7 more than most. If a sufficient alphabet of effects (I am using the Alephs, Beths, Gimels, and Daleths of the Hebrew as token starters only) were to be accumulated and defined, the actions of new materials might someday be more exactly documented. Could depression, euphoria, and disinhibition for example, all be eventually seen as being made up of their component parts, each contributing in some measured way to the sum, to the human experience? The psychologists of the world would be ecstatic. And drugs such as ALEPH-7 might be useful in helping to define one of these parts.

#8 ARIADNE; 4C-DOM; BL-3912; DIMOXAMINE; 1-(2,5-DIMETHOXY-4-METHYLPHENYL)-2-AMINOBUTANE; 2,5-DIMETHOXY-a-ETHYL-4-METHYLPHENETHYLAMINE

SYNTHESIS: In 50 mL of benzene there was dissolved 31.6 g 2,5-dimethoxy-4-methylbenzaldehyde (see recipe for 2C-D for its preparation), 20.2 mL 1-nitropropane, and 6 mL cyclohexylamine. This solution was held at reflux in a Dean Stark apparatus for 24 h, effectively removing the water of reaction. Upon cooling, there was deposited 19.6 g of 1-(2,5-dimethoxy-4-methylphenyl)-2-nitro-1-butene as brilliant orange crystals. The mp, after recrystallization from MeOH, was 114-115 deg C and a second recrystallization increased the mp another 2 deg C. Anal. (C13H17NO4) C,H,N.

A suspension of 12.5 g LAH in 600 mL anhydrous THF was stirred magnetically, and brought up to a reflux. To this there was added, dropwise, 15.0 g 1-(2,5-dimethoxy-4-methylphenyl)-2-nitro-1-butene dissolved in 150 mL THF. Refluxing was continued for 15 h and, after cooling, the excess hydride was decomposed by the addition of 12.5 mL H2O. The inorganic salts were made loose and granular by the addition of 12.5 mL 15% NaOH followed by an additional 37.5 mL H2O. These solids were removed by filtration, and the filter cake was washed with THF. The combined filtrate and washings were stripped of solvent under vacuum. The residue was dissolved in anhydrous Et2O, and treated with hydrogen chloride gas, yielding 1-(2,5-dimethoxy-4-methylphenyl)-2-aminobutane hydrochloride (ARIADNE) as white crystals which, after recrystallization from IPA, weighed 11.4 g and had a mp of 232.5-234.5 deg C. Anal. (C13H22ClNO2) C,H,N,Cl. The racemic mixture was resolved into its optical isomers by the formation of salts with (+)-2beta-nitrotartranilic acid (to give the "S" isomer) or with (+)-2beta-chlorotartranilic acid (to give the "R" isomer). The "R" isomer can also be prepared by the reductive amination of 1-(2,5-dimethoxy-4-methylphenyl)-2-butanone (from the above nitrostyrene and elemental iron) with (+)-a-methyl benzylamine followed by the hydrogenolysis of the benzyl group.

DOSAGE: as psychedelic, unknown.

DURATION: short.

QUALITATIVE COMMENTS: (with 12 mg) I believe that my mood has distinctly improved, and my sleep that evening was excellent. This is physically benign.

(with 32 mg) There was some sort of threshold that lasted for a couple of hours.

(with 25 mg of the "R" isomer) There is the alert of a psychedelic, with none of the rest of the package. Perhaps a bit of paranoia. And

by the fifth hour everything is largely gone.

EXTENSIONS AND COMMENTARY: How does one discover a new drug for a malady that does not exist in experimental animals? Drugs that interfere with sleep, or with appetite, or with some infecting bacterium, are naturals for animal screening, in that animals sleep, eat, and can be easily infected. But there are lots of syndromes that involve a state of mind, and these are uniquely human. Many of the psychopharmacological anti-this or anti-that agents address ailments such as anxiety, psychosis, paranoia, or depression, which are only known in man. So how does one discover a new drug in areas such as these? If one has in hand a drug that is known to be effective in one of these human ailments, an animal assay can be set up to give some measurable response to that specific drug, or a biochemical property can be rationalized as being related to a mechanism of action. And with the known drug as a calibration, and restricting your search to structurally related compounds, you can find structural relatives that give the same responses.

But how does one find a new class? One way is to kind of stumble into it as a side-line of human experimentation with new psychedelics. But it is really difficult to pick up the clues as to what will be a good anti-depressant if you are not depressed. This compound, to which I had given the name of ARIADNE as the first of my ten "classic ladies" (I'll say more about them later), was not really a stimulant of any kind, certainly it was not a psychedelic, and yet there was something there. It had been explored rather extensively as a potential psychotherapeutic ally by a friend of mine. He said that there seemed to be some value in a few of his patients who had some underlying depression, but not much of anything with the others. So, I decided to call it an anti-depressant. I had mentioned some of this history one time when I was giving an address at a conference on the East Coast, and my host (who happened to be the research director at a large pharmaceutical house) asked if I would send him a sample. His company did many animal tests, one of which showed that it was not hallucinogenic (a cat whose tail erected dramatically with DOM did nothing with ARIADNE) and another that showed re-motivation (some old maze-running monkeys who had decided not to run any more mazes changed their minds with ARIADNE).

So patents were obtained for the "R" isomer, the more effective isomer, covering its use for such things as the restoring of motivation in senile geriatric patients. And a tradename of Dimoxamine was assigned it, despite several voices that held out for Ariadnamine. But it didn't have what was needed to make it all the way to the commercial market.

Many, many analogues of ARIADNE have been made, and for a variety of reasons. In the industrial world there is research backup carried out, not only for the discovery of new things, but also for patent protection of old things. Several dozen analogues of ARIADNE have been made and pharmacologically evaluated, and some of them have been put into the published literature. The major points of variation have been two: keep the 4-position methyl group intact, and make the variations on the alpha-carbon (propyl, butyl, dimethyl, phenyl, benzyl, phenethyl, etc. Q an extensive etc.) or: keep the alpha-position ethyl group intact and make the variations on the 4-position (chloro, iodo, methylthio, carboxy, etc. Q again, an extensive etc.).

Some of these analogues I had made, and sent in for animal screening. The high potency of DOB suggested the bromo-counterpart of ARIADNE. The making of this entailed the proteo counterpart, 1-(2,5-dimethoxyphenyl)-2-aminobutane. Reaction of 2,5-dimethoxybenzaldehyde with nitropropane in benzene in a Dean Stark apparatus with cyclohexylamine as a catalyst produced 1-(2,5-dimethoxyphenyl)-2-nitrobutene, which crystallized as orange crystals from MeOH with a mp of 47-47.5 deg C. Anal. (C12H15NO4) C,H,N. This was reduced to the amine 1-(2,5-dimethoxyphenyl)-2-aminobutane with LAH in ether, and this gave a hydrochloride salt with a mp of 172-174 deg C after recrystallization from acetonitrile. The free base of this compound was brominated in acetic acid to give 1-(2,5-dimethoxy-4-bromophenyl)-2-aminobutane which yielded a white hydrochloride salt with a mp of 204-206 deg C following recrystallization from IPA. The isomeric non-brominated analogue, 1-(3,4-dimethoxyphenyl)-2-aminobutane was made and explored by the Chemical Warfare group at Edgewood Arsenal; its code number is EA-1322.

Several of the alpha-ethyl analogues of ARIADNE were N,N-dialkylated, and were target compounds for halogenation with radio-iodine or radio-fluorine, for evaluation as potential brain blood-flow indicators. In these studies. all examples followed a common flow diagram. The reaction of the appropriate benzaldehyde and nitropropane, using N,N-dimethylethylenediamine as a catalyst and following recrystallization from MeOH, gave the corresponding 1-aromatic-2-nitro-1-butene (the nitrostyrene) which, by reduction with elemental iron, gave the corresponding 2-butanone (which was distilled at about 0.3 mm/Hg). This led, by reductive amination with dimethylamine hydrochloride and sodium cyanoborohydride, to the corresponding N,N-dimethyl product which was distilled at about 0.3 mm/Hg and which, in no case, either formed a solid HCl salt or reacted with carbon dioxide from the air. From 2,4-dimethoxybenzaldehyde, the nitrostyrene appeared as yellow crystals, the ketone as a white oil, and the product N,N-dimethyl-1-(2,4-dimethoxyphenyl)-2-aminobutane as a white oil. From 2,5-dimethoxybenzaldehyde, the nitrostyrene formed bright yellow crystal, the ketone was an off-white oil, and the product N,N-dimethyl-1-(2,5-dimethoxyphenyl)-2-aminobutane was a white oil. From 3,5-dimethoxybenzaldehyde, the nitrostyrene formed pale yellow crystals that discolored on exposure to the light, the ketone was an off-white clear oil, and the product N,N-dimethyl-1-(3,5-dimethoxyphenyl)-2-aminobutane was a white oil. From 2,6-dimethoxybenzaldehyde, the nitrostyrene was obtained as orange crystals, and was not pursued further.

A number of ARIADNE analogues have been made, or at least started, purely to serve as probes into whatever new areas of psychopharmacological activity might be uncovered. One of these is a HOT compound, and one is a TOM compound, and a couple of them are the pseudo (or near-pseudo) orientations. The HOT analogue was made from the nitrostyrene precursor to ARIADNE itself, reduced not with LAH or AH (which would give the primary amine), but rather with sodium borohydride and borane dimethylsulfide. The product, 1-(2,5-dimethoxy-4-methylphenyl)-N-hydroxy-2-aminobutane hydrochloride, was a white crystalline material. The 5-TOM analogue got as far as the nitrostyrene. This was made from 2-methoxy-4-methyl-5-(methylthio)benzaldehyde (see under the 5-TOM recipe for its preparation) and nitropropane in acetic acid, and gave bright yellow crystals. The true pseudo-analogue is the 2,4,6-trimethoxy material based on TMA-6, which is the "real" pseudo-TMA-2. The nitrostyrene from 2,4,6-trimethoxybenzaldehyde and nitropropane crystallized from MeOH/CH3CN as fine yellow crystals, and this was reduced with AH in cold THF to

1-(2,4,6-trimethoxyphenyl)-2-aminobutane which was a bright, white powder.

And the near-pseudo analogue?

First, what is near-pseudo? I have explained already that the "normal" world of substitution patterns is the 2,4,5. Everyone knows that that is the most potent pattern. But, the 2,4,6 is in many ways equipotent, and has been named the pseudo-stuff. The "real," or "true" pseudo-stuff. So what is the "near" pseudo-stuff? I am willing to bet that the rather easily obtained 2,3,6-trisubstitution pattern, and the much more difficult to obtain 2,3,5-substitution pattern, will produce treasures every bit as unexpected and remarkable as either the 2,4,5- or the 2,4,6- counterparts. These are neither "real" nor "pseudo," but something else, and I will find a name for them when the time comes, something weird from the Greek alphabet. And this will double again the range of possible exploration. The TMA-5 analogue mentioned came from 2,3,6-trimethoxybenzaldehyde and nitropropane using cyclohexylamine as a catalyst (yellow-orange solids) which was reduced to the amine with AH. This hydrochloride salt is an air-stable white powder. All of these materials remain unexplored.

Somewhere in the wealth of compounds implicit in the many structural variables possible (the normal versus the pseudo versus the near-pseudo patterns, coupled with the wide variety of promising substituents that can be placed on the 4-position, together with the availability of the the unexplored members of the Ten Classic Ladies harem), it would seem inescapable that interesting compounds will emerge.

Just what is this all about the ten "Classic Ladies?" In the chemical struc-ture of DOM, there is a total of nineteen hydrogen atoms. Some of these are indis-tinguishable from others, such as the three hydrogen atoms on a methyl group. But there are exactly ten "types" of hydrogen atoms present. And, not having much, if any, intuition as to just why DOM was so powerful a psychedelic, I decided to systematically replace each of the ten unique hydrogens, one at a time of course, with a methyl group. And I planned to give the resulting materials the names of famous ladies, alphabetically, as you walk around the molecule.

ARIADNE was the first of these, the methyl for a hydrogen atom on the methyl group of the amphetamine chain. It was Ariadne who gave the long piece of thread to Theseus to guide him through the mazes of the Labyrinth so he could escape after killing the Minotaur. The record is fuzzy as to whether, after the successful killing, she went with him, or let him go on alone. A methyl group on the nitrogen atom produced BEATRICE. There is the legendary Beatrijs of the Dutch religious literature of the 14th century, and there is the Beatrice from Beatrice and Benedict (of Berlioz fame). But the one I had in mind was the lady from Florence whom Dante immortalized in the Divina Commedia, and she is entered under her own name in this footnote. Replacing the alpha-hydrogen of DOM with a methyl group would give the phentermine analogue which is named CHARMIAN. You may be thinking of Cleopatra's favorite attendant, but I was thinking of the sweet wife of a very dear friend of mine, a lady who has been in a state of gentle schizophrenia for some forty years now. The MDA analogue of CHARMIAN has been described in this foornote under the code name of MDPH. CHARMIAN, herself, has been synthesized and is of very much reduced potency in animals, as compared to DOM. It has not been tried in man as far as I know.

The two beta-hydrogen atoms of DOM are distinct in that, upon being replaced with methyl groups, one would produce a threo-isomer, and the other an erythro-isomer. I have named them DAPHNE (who escaped from Apollo by becoming a laurel tree which was, incidentally, named for her) and ELVIRA (who might not be too well known classically, but whose name has been attached to Mozart's 21st piano concerto as its slow movement was used as theme music for the movie Elvira Madigan). I don't know if either of this pair has been made Q I started and got as far as the cis-trans mixture of adducts betweeen nitroethane and 2,5-dimethoxy-4-methylacetophenone. Whoever finally makes them gets to assign the names. I had made and tested the corresponding homologues of DMMDA that correspond to these two ladies.

And there are five positions (2,3,4,5 and 6) around the aromatic ring, each of which either carries a hydrogen atom or a methyl group that has a hydrogen atom. There is the 2-methoxy group which can become a 2-ethoxy group to produce a compound called FLORENCE. Her name is the English translation of the Italian Firenze, a city that, although having a female name, has always seemed thoroughly masculine to me. There is the 3-hydrogen atom which can become a 3-methyl group to produce a compound called GANESHA. This is a fine elephant-headed Indian God who is the symbol of worldly wisdom and also has been seen as the creator of obstacles. Here I really blew it; the Classic Lady turned out to be a Classic Gentle-man; not even the name is feminine. There is the 4-methyl group which can become a 4-ethyl group to produce a compound called HECATE who presided over magic arts and spells. There is the 5-methoxy group which can become a 5-ethoxy group to produce a compound called IRIS, who is the Goddess of the rainbow. And there is the 6-hydrogen atom which can become a 6-methyl group to produce a compound called JUNO, who is pretty much a lady's lady, or should I say a woman's woman.

GANESHA, 2,5-dimethoxy-3,4-dimethylamphetamine has been made, and has proven to be an extraordinary starting point for a large series of potent phenethylamines and amphetamines which are described in this book. HECATE was given a synonym early in this process, and is now known as DOET (2,5-dimethoxy-4-ethylamphetamine). IRIS has also been entered under her name, and the other ethoxy homologue, FLORENCE, would be easily made based on the preparation of the phenethylamine analogue, 2CD-2ETO. Perhaps it has already been made somehow, somewhere, as I have noted that I have claimed its citrate salt as a new compound in a British patent. And, finally, JUNO (3,6-dimethoxy-2,4-dimethylamphetamine) has been made (from 2,5-dimethoxy-m-xylene, which was reacted with POCl3 and N-methylformanilide to the benzaldehyde, mp 53-54 deg C, and to the nitrostyrene with nitroethane, mp 73-74 deg C from cyclohexane, and to the final amine hydrochloride with LAH in THF). Rather amazingly, I have had JUNO on the shelf for almost 14 years and have not yet gotten around to tasting it.
