Procedure

5-Oxo-1-(phenylmethyl)-proline (0.176 g, 0.80 mmol, prepared as described below) was dissolved in dichloromethane (3 ml) and to this was added 1-hydroxybenzotriazole (0.119 g, 0.88 mmol), triethylamine (0.113 ml, 0.81 mmol), [(2-chloro-4-fluorophenyl)methyl]amine (0.134 g, 0.84 mmol) and N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (0.169 g, 0.88 mmol) under an atmosphere of argon. The mixture was stirred at room temperature overnight. The mixture was diluted with dichloromethane and washed sequentially with 2M aqueous hydrogen chloride and saturated aqueous sodium hydrogen carbonate. The organic layer was filtered through a phase separator and then evaporated to give the crude product. The crude material was purified by mass-directed automated HPLC to give pure N-[(2-chloro-4-fluorophenyl)methyl]-5-oxo-1-(phenylmethyl)-prolinamide (0.112 g) as a white solid. LC/MS [M+H]+=361.2, retention time=2.55 minutes.
