N,N-Dimethyl-MDA · 3,4-Methylenedioxy-N,N-dimethylamphetamine
SYNTHESIS: To a well stirred solution of 9.7 g dimethylamine hydrochloride in 50 mL MeOH there was added 3.56 g of 3,4-methylenedioxyphenylacetone (see under 2O and made strongly acidic with an excess of HCl. After washing with 2×100 mL CH2Cl2 the aqueous phase was made basic with 25% NaOH, and extracted with 3×100 mL CH2Cl2. Removal of the solvent under vacuum yielded a nearly colorless oil that was distilled at 85–90 °C at 0.3 mm/Hg. There was obtained 1.5 g of a water-white oil that was dissolved in 8 mL IPA, neutralized with concentrated HCl and then diluted with 10 mL anhydrous Et2O. The slightly turbid solution deposited a light lower oily layer which slowly crystallized on scratching. With patience, an additional 75 mL of Et2O was added, allowing the formation of a white crystalline mass. This was removed by filtration and washed with additional Et2O. After air drying there was obtained 1.3 g of 3,4-methylenedioxy-N,N-dimethylamphetamine hydrochloride (MDDM) with a mp of 172–173 °C. The NMR spectrum (60 mH) of the hydrochloride salt (in D2O and with external TMS) was completely compatible with the expected structure. The signals were: 1.25, 1.37 (d) CCH3, 3H; ArCH2 under the N(CH3)2, 2.96, 8H; CH (m) 3.65; CH2O2 (s) 6.03 2H; ArH 6.93 (3H). Anal: (C12H18ClNO2) N.
DOSAGE: greater than 150 mg.
QUALITATIVE COMMENTS: (with 150 mg) “No effects whatsoever.”
(with 150 mg) “The effects, if any, were so-so. Perhaps a threshold. But my libido was non-existent for three days.”
(with 550 mg) “I took 550 milligrams of it Saturday night and I had a pretty bad trip. On a scale of positive 10 to negative 10 it was about a negative 6. It really downed me. Two other friends took 200 milligrams. They found it very pleasant after about 20 minutes. It was a plus 3 [on the -10 to +10 scale]. Then it wore off a little bit; and then, 4 hours later, it hit them even stronger and was about a plus 5.”
(with 1000 mg) “I took up to a gram of it and absolutely nothing.”
EXTENSIONS AND COMMENTARY: I cannot attest for the actual drug that had been used in the two larger-dose reports above. These are from an anonymous source associated with clandestine syntheses. If this material does eventually prove to be active, it is going to require a pretty hefty dose. But it may well have some activity, as there have been reports in the forensic literature of its preparation, or at least its intended preparation, in illicit laboratories. It seems unlikely that much effort would be directed towards the synthesis of a completely inactive compound.
The reduced potency of MDDM has been exploited in an unexpected way. Based on the premise that the dialkylation of the amine group of amphetamine makes the parent compound intrinsically less active but without interfering with its ability to enter the brain, a large number of materials have been explored to take advantage of this very property. There is a need in medical diagnosis for agents that can allow various organs of the body to be visualized. One of the most powerful modalities for this work is the positron camera, and the use of the unusual properties of the positron that allow it to work. In the art of positron emission tomography (PET), an emitted positron (from a radioactive and thus unstable atom) will quickly interact with a nearby electron and all mass disappears with the complete conversion to energy. The detection of the produced pair of annihilation gamma rays will establish with great exactness the line along which this interaction occurred. So if one were to put an unstable atom into a compound that went to the tissue of the brain, and this atom were to decay there, the resulting gamma rays would allow a “photograph” to be made of the brain tissue. One could in this way visualize brain tissue, and observe abnormalities.
But what is needed is a molecule that carries the unstable atom (and specifically one that emits positrons) and one which goes to the brain as well. One of the very best unstable atoms for the formation of positrons is iodine, where there is an isotope of mass 122 which is perfect for these needs. And, of course, the world of the psychedelic drugs is tailor-made to provide compounds that go to the brain. But, the last thing that the physician wants, with the diagnostic use of such tools, would be to have the patient bouncing around in some turned-on altered state of consciousness.
So the completely logical union of these requirements is to take a compound such as

About PiHKAL · info
This version of Book II of PiHKAL is based on the Erowid online version, originally transcribed by Simson Garfinkle and converted into HTML by Lamont Granquist. I drew also on “Tyrone Slothrop’s” (Unfinished) Review of PIHKAL to enumerate the many analogues mentioned in PiHKAL but not described at length. Many, many others have since been added.
I have tried here to expunge any artifacts introduced by the earlier transcriptions and restore the typographic niceties found in the printed edition. I’ve also made minor changes to some chemical names in line with current nomenclature practice. Typically the change is little more than expanding a prefix or setting it in italics. The history page has further details.
“At the present time, restrictive laws are in force in the United States and it is very difficult for researchers to abide by the regulations which govern efforts to obtain legal approval to do work with these compounds in human beings.“No one who is lacking legal authorization should attempt the synthesis of any of the compounds described in these files, with the intent to give them to man. To do so is to risk legal action which might lead to the tragic ruination of a life. It should also be noted that any person anywhere who experiments on himself, or on another human being, with any of the drugs described herein, without being familiar with that drug’s action and aware of the physical and/or mental disturbance or harm it might cause, is acting irresponsibly and immorally, whether or not he is doing so within the bounds of the law.”

PiHKAL is the extraordinary record of the authors’ years exploring the chemistry and transformational power of phenethylamines. This book belongs in the library of anyone seeking a rational, enlightened and candid perspective on psychedelic drugs.
Though Sasha and Ann have put Book II of PiHKAL in the public domain, available to anyone, I strongly encourage you to buy a copy. We owe them — and there’s still nothing quite like holding a real book in your hands.
PiHKAL (ISBN 0-9630096-0-5) is available for US$24.50 (plus $10 domestic first-class shipping) from Transform Press.Transform Press,
