Reaction Steps

To a solution of trifluoro-methanesulfonic acid 3-[1-benzyl-3-(4-diethylcarbamoyl-phenyl)-piperidin-3-yl]-phenyl ester (0.40 g, 0.69 mmol) in DMF (8 mL) was added zinc cyanide (0.057 g, 0.49 mmol) and tetrakis triphenylphosphine palladium (0.16 g, 0.14 mmol). The reaction was stirred under a nitrogen atmosphere at 90° C. for 5 hours. The mixture was cooled to room temperatures and it was diluted with diethyl ether (30 mL). The organic layer was washed with brine (5×10 mL), dried (MgSO4) and concentrated. Purification with hexanes/EtOAc (1:1) afforded 0.28 g of 4-[1-benzyl-3-(3-cyano-phenyl)-piperidin-3-yl]-N,N-diethyl-benzamide.
