A mixture of 2.8 g of 4-diphenylmethyl-1-(3-phthalimidopropyl)piperidine (prepared as described in Preparation 44') and 0.90 g of hydrazine hydrate in 100 ml of ethanol was heated under reflux for 2 hours. At the end of this time, the mixture was cooled to room temperature and filtered. The mixture was concentrated by evaporation under reduced pressure, to give 0.93 g (yield 47%) of the title compound as an oil.
