Procedure

To a solution of 0.2 g of 4-(3-Aminomethyl-phenyl)-1-tert-butoxycarbonyl-piperidine-4-carbonitrile in 15 ml of dichloromethane was added a few drops of triethylamine followed by a few drops of benzyl chloroformate. The mixture was stirred for 1 hour at room temperature and was poured into aqueous sodium carbonate and was extracted with dichloromethane. The organic layer was dried over magnesium sulfate and was filtered. The filtrate was evaporated and the residue was used directly in the next step without further purification: 1H-NMR (300 MHz, CDCl3)δ (TMS) 1.39-1.52 (m, 9H), 1.80-2.16(m, 4H), 3.08-3.42(m, 4H), 4.19-4.50(m, 2H), 5.08-5.13(d, 2H), 7.28-7.79(m, 9H), MS (ESI) m/e 450 (M+H)+.
