実験手順

A mixture of 1-benzyl-4-cyano-4-(3-methylphenylamino)-piperidine (7.6 g) and 90% sulfuric acid (53 mL) was heated 70° C. until all the solid dissolved (~1 h). The resultant mixture was stirred at the temp. for 30 min., and poured into a mixture of ice (80 g) and concentrated ammonium hydroxide (75 g). The solution was basified with ammonium hydroxide, and extracted with chloroform. The organic extract was washed with brine, dried over anhydrous sodium sulfate, filtered, and concentrated under vacuum to provide the title compound.
