Reaction Steps

3-(4-(4-chlorophenyl)-4-cyanopiperidin-1-yl)propylcarbamic acid tert-butyl ester (0.150 g, 5.39 mmol) in conc. H2SO4 (1 mL) was stirred at room temperature for 30 hours. The solution was concentrated, neutralized with 10% KOH solution and extracted into 25 mL of dichloromethane. The organic layer was dried over sodium sulfate, filtered and concentrated to give 0.185 g (79%) of 1-(3-aminopropyl)-4-(4-chlorophenyl)piperidine-4-carboxamide which was used as such for the subsequent step.
