Procedure

Sodium hydride (51 mg) was dissolved in dimethylformamide (5 mL), and the solution was cooled to 0° C. To the solution was added the 4-[(4′-trifluoromethylbiphenyl-2-carbonyl)amino]phenylacetic acid ethyl ester (500 mg) obtained in Example 1e), and the mixture was stirred for one hour. After addition of iodomethane (183 mg), the mixture was stirred at room temperature for 3 hours and water was then added. The reaction solution was concentrated, diluted with ethyl acetate, and washed with water. The resulting solution was dried over sodium sulfate and purified by column chromatography on silica gel with hexane:ethyl acetate=4:1 to give the title compound (141 mg).
