.. the way I understand it, the xylene that is sold retail is predominatly m-xylene followed by p-xylene then o-xylene. It seems to me that oxidation under neutral conditions with one half part potassium permanganate, and utilizing Al2O3 as a solid support to prevent over-oxidation, should give, in the respective order, m-tolualdehyde, p-tolualdehyde, and o-tolualdehyde.
Bromination of this mixture, and then subsequent reaction with copper and sodium methoxide should give a mixture of predominatly 2-methoxy-4-methylbenzaldehyde, followed by 3-methoxy-4-methylbenzaldehyde and 2-methyl-5-methoxybenzaldehyde.
I believe that all of these aldehydes would lead to active isopropylamines from the usual workup involving EtNO2 condensation followed by reduction, except for perhaps, the 2-methyl-5-methoxybenzaldehyde, originating from o-xylene, which would hopefully only be a small portion of the xylene of commerce.
3-methoxy-4-methylamphetamine, or MMA, has already been shown to be quite active in the 40-60 mg range and I would expect the isomer 3-methyl-4-methoxyamphetamine to be just as active, since 3-Me isomers of DOM are also potent.
... OTC MMA from just a few simple reactions, could this be true? Any thoughts on this or am I off base here?
