Reaction Steps

3.76 g of 2-(3,4-dimethoxyphenyl)-2-(2,3-epoxypropyl)-m-dithiane-1,1,3,3-tetraoxide are heated at reflux for 18 hours under argon with 50 ml of ethanol, 30 ml of chloroform and 1.95 g of N-methyl-homovetratrylamine. After evaporation of the solvent, the residue is chromatographed on silica gel with chloroform/ethanol (98:2). The oil obtained is dissolved in acetone and treated with an equivalent amount of anhydrous oxalic acid. The precipitate is filtered off and recrystallized from methanol/acetone. The racemic α- (3,4-dimethoxyphenethyl)-methylamino!-methyl-2-(3,4-dimethoxyphenyl)-m-dithiane-2-ethanol-1,1,3,3-tetraoxide oxalate (1:1) obtained crystallizes with 1 mol of acetone and melts at 162°-164° C.
