Procedure

5-oxo-1-phenyl-proline (0.047 g, 0.23 mmol, prepared as described below) was dissolved in dichloromethane (˜2 ml) and dimethylformamide (1 ml) and to this was added 1-hydroxybenzotriazole (0.034 g, 0.25 mmol), [(2-chloro-4-fluorophenyl)methyl]amine (0.040 g, 0.25 mmol), N-ethyl morpholine (0.032 ml, 0.25 mmol) and N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (0.048 g, 0.25 mmol). The mixture was stirred at room temperature for 4.5 hrs. The mixture was diluted with more 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-phenyl-prolinamide (0.032 g) as a white solid. LC/MS [M+H]+=347.1, retention time=2.51 minutes.
