ethoxybenzaldehyde, and the heat will not be far behind.
Further chemical supply problems arise from this method's use of
large amounts of anhydrous ether or THF in the LiAlHj reduction.
This too will be duly noted by the heat, especially in combination with
buying LiAlHt.
A much more low-profile synthetic route is possible using
calamus oil as the raw material. A couple of patents granted in the late
80s have completely changed the field of psychedelic amphetamine
manufacture from the way Dr. Shulgin knew it during his days of
cooking in the 60s. Previous to the publication of these patents, the
Knoevenagel condensation of benzaldehydes to yield the nitroalkene,
followed by the reduction of the nitroalkene to the amphetamine, was
far superior to an alternative route making use of the common
essential oils.
Many essential oils have as major components substituted
allylbenzenes. For example, sassafras oil is 80-90% safrole:
The alternative route was to take this substituted allylbenzene,
move the double bond to Organic Spirulina the propenyl position by heating with
anhydrous alcoholic KOH, yielding in the case of safrole, isosafrole.
Then a messy, tedious and low-yield reaction was used to convert this
propenylbenzene to the corresponding phenylacetone. All we veteran
speed cooks love phenylacetones, because they offer the cleanest and
best route to the amphetamines, but the old-fashioned method Spirulina Health Benefit of

converting propenylbenzenes to phenylacetones made this route
impractical:
My own experience with this reaction dates to the early 80s, when I
decided to torment myself by trying it. Detailed cooking procedures
using it can be found in Pikhal under MDMA. My experience with
the KOH isomerization was that the conversion of safrole to isosafrole
went cleanly at about 100% yield, as long as traces of moisture were
excluded from the reaction.
The conversion of isosafrole to
methylenedioxy-phenylacetone is another matter.
The yields are low, a
lot of work is required because the formic acid and hydrogen peroxide
must be removed from the reaction mixture under a vacuum before
final treatment with sulfuric acid solution to yield the phenylacetone,
and these vapors corrode the aspirator supplying the vacuum. This
method stinks!
Two patents dating to the late 80s, and to a lesser extent a journal
article dating back to 1970, have turned the situation around. The first
patent I will cite is US patent 4,638,094, titled "A Process for
Producing Phenylacetones." This patent reveals, using many different
examples over the course of 36 pages, the best general method for
converting allylbenzenes to the corresponding phenylacetone in very
high yields.
This procedure reacts the allylbenzene (for example safrole, as
obtained in pure form by vacuum distilling sassafras oil) with
methylnitrite in methanol solution containing water and a palladium
catalyst to yield the phenylacetone. The palladium catalys
