Participants

Reaction Steps

The 1-methyl-3-(3-methylphenacyl)piperidine obtained above was dissolved in about 100 ml of diethyl ether. The resulting solution was added to a diethyl ether solution of maleic acid. The solvent was decanted from the resulting solid which was taken up in hot acetone. The resulting solution was cooled and diluted with diethyl ether. The crystals which formed were isolated by filtration, washed with diethyl ether, and recrystallized from acetone/diethyl ether to give 12.6 g of 1-methyl-3-(3-methylphenacyl)piperidine, maleate salt, mp 92°-94°. The following elemental analysis was obtained:
