実験手順
16.8 Grams of phthalic anhydride and 21.6 grams of 4-amino-1-benzyl-piperidine were stirred together while they were being heated in an oil bath at 150° C. for 30 minutes. On cooling, the resulting glassy solid was heated with 400 milliliters of methanol to give 26.5 grams of 1-benzyl-4-phthalimidopiperidine. Melting point: 154°-7° C.
