A mixture of 1-methyl-2-oxo-4-imidazolidinecarboxylic acid (144 mg, 1 mmol), N-ethyl morpholine (0.767 ml, 6.00 mmol), 1-hydroxybenzotriazole hydrate (184 mg, 1.200 mmol) and 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (230 mg, 1.200 mmol) in dichloromethane (18 ml) was stirred at room temperature for 10 minutes. A solution of {[2-chloro-3-(trifluoromethyl)phenyl]methyl}amine (210 mg, 1.000 mmol) in dichloromethane (2 ml) was added and the reaction stirred at room temperature for hours. The mixture was diluted with dichloromethane and the mixture was washed with 3N citric acid solution. The organic phase was separated, washed with brine, dried and evaporated. The residue was purified by mass-directed automated HPLC to give the N-{[2-chloro-3-(trifluoromethyl)phenyl]methyl}-1-methyl-2-oxo-4-imidazolidinecarboxamide (150 mg, 55%). LC/MS [M+H]+=336, retention time=2.22 minutes.
