1914. Assigned to E. Merck in Darmstadt.
- A chemical process is described for the conversion of several allyl- and
propenyl-aromatic compounds to the corresponding beta-or
alpha-bromopropanes. These, in turn, react with ammonia or primary amines
to produce the corresponding primary or secondary propylamines.
Specifically, safrole was reacted with aqueous HBr, and the impure reaction
product reacted with alcoholic methylamine to produce MDMA in an unstated
yield. Also described and characterized are MDA and DMA, as well as the
corresponding 1-phenyl-1-aminopropanes. No pharmacology is mentioned.

- A chemical conversion of MDMA to its formyl derivative, and the properties
of the latter, are described. No pharmacology is mentioned.

- A chemical procedure is given for the conversion of safrole to the
beta-bromopropane with HBr, and its subsequent conversion with alcoholic
methylamine to MDMA. 4-Allylveratrole was similarly converted to

- Some twelve impurities have been described and identified in samples of
illicitly prepared MDMA and MDA. Their role as markers for the synthetic
routes used, or for connercting different lots of the drugs, is discussed.

- Twenty two homologues and analogs of MDA were synthesized and their
physical properties presented. Twelve of them were assayed in man as
psychotomimetic agents. Three of them were found to be active: MDMA with a
human potency of between 100 and 160 mg orally; MDE somewhat less potent
with a dosage requirement of 140-200 mg orally; and MDOH, which was similar
to MDMA in potency. Some animal pharmacology is reviewed, and a comparison
between MDMA and MDA (toxicology, CNS pharmacology, and human
effectiveness) is tabulated.

- Piperonal is a most desirable precursor to piperony methyl ketone (PMK)
which can, in turn, be converted directly to either MDA or MDMA. This is a
synthetic procedure for the preparation of piperonal (heliotropin) from the
precursor catechol (pyrocatechol).

- The conversion of safrole to piperonylacetone is described, using formic
acid and hydrogen peroxide, in acetone. The yield is satisfactory, and this
is probably the most direct and efficient conversion of a natural product
to an immediate precursor to MDMA.

- Tritium-labelled MDMA was synthesized from MDA by reaction with radioactive
methyl iodide in a 60% yield. The optical isomers were separated on a
chiral HPLC column.

- Several clandestine laboratories have been seized, revealing the illicit
preparation of not only MDMA, but the N-ethyl (MDE), the N-propyl (MDPR),
the N-isopropyl (MDIP) and the N,N-dimethyl (MDDM) homologues. These were
all synthesized by the NaCNBH3 reduction method from the appropriate amine
salt and piperonylacetone. Also, the N-ethyl-N-methyl, and the N,N-diethyl
homologues were found, prepared by catalytic hydrogenation.

- A high yield procedure is described, for the conversion of an allylbenzene
to the corresponding phenylacetone. Specifically, the MDMA precursor
3,4-methylenedioxyphenylacetone is prepared in a 95% yield from safrole and
butyl nitrite, in the presence of palladium bromide.

- The commercial availability and overt misrepresentation of
3,4-methylenedioxybenzylacetone as 3,4-methylenedioxyphenylacetone might
well suggest that an unsuspecting attempt to synthesize MDMA may yield a
new and unexplored base,
1-(3,4-methylenedioxyphenyl)-3-(methylamino)butane. This compound was
synthesized, and characterized in comparison to MDMA. The analogous
relationship between MDA and its comparable homologue,
1-(3,4-methylenedioxyphenyl)-3-aminobutane, was also explored.

is also offered.
