The synthesis and resolution of a Tolperisone metabolite ((3'-hydroxy-4'-me
thylphenyl)-2-methyl-3-(piperidine-1-yl)-1-propane-1-one, M1) is described.
Racemic M1 was subjected to resolution by the enantiomers of camphor-10-su
lfonic acid. Absolute configuration was determined by X-ray diffraction ana
lysis. Enantiomeric excesses were determined by H-1 NMR spectroscopy. (C) 2
