Didrex, benzphetamine, futher described below, is easily made by the addition of benzyl chloride to d-desoxyphedrine, whatever that is, in the presence of sodium carbonate in non polar..

Now as it so happens, my evil neighbor Marvin has stumbled across a cache of this in the closet of his deceased great aunt Mergatroid, whose obesity problem is legend hereabouts: supposedly she was consuming prodigious quantities of the stuff to try to lose excess poundage, to no apparent effect..
Anyway, Marvin wants to know how to undo the benzyl chloride effect: he says he wants to have the pure desoxy-shit for some reason:
any help appreciated...
( I dida search for didrex afore doing this post: zero results
I'll 'research for benzphetamine: )
