実験手順
14.1 g (0.05 mol) of N-(cyanomethyl)-4-(p-fluorobenzoyl)-piperidine are dissolved in 1.5 liters of glacial acetic acid and 30 ml of concentrated hydrochloric acid and hydrogenated together with 2 g of platinum oxide in a hydrogen atmosphere. After 6 hours, the theoretical amount of 2.25 liters of hydrogen is absorbed. The catalyst is then filtered off with suction and the filtrate is concentrated to approximately 30 ml in a water-jet vacuum. There is added to the resulting crystal mass 5 ml of isopropanol and 15 ml of ether and filtration with suction is carried out. After filtration with suction and drying, N-(2-aminoethyl)-4-(p-fluorobenzoyl)-piperidine hydrochloride is obtained which, after recrystallisation from methanol, melts at 265° with decomposition.
