Procedure

To a solution of 5-[(2,5-difluorophenyl)[(4-fluorophenyl)sulfonyl]methyl]-4-methylpyridine-2-carboxylic acid (337 mg, 0.80 mmol) obtained in Example 12 in methylene chloride (8 ml), 2-(methylamino)ethanol (0.077 ml, 0.96 mmol), 1-hydroxybenzotriazole (130 mg, 0.96 mmol), 4-methylmorpholine (0.194 ml, 1.76 mmol), and 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (184 mg, 0.96 mmol) were added at room temperature. After stirring for 24 hours at room temperature, the reaction mixture was washed with 1 N hydrochloric acid. The organic layer was dried over anhydrous sodium sulfate and filtered, then the filtrate was concentrated under reduced pressure, and the resulting residue was subjected to flash silica gel chromatography. The fraction obtained from an elution with ethyl acetate was concentrated under reduced pressure, and the resulting residue was washed with a mixed solvent of ethanol and diethyl ether, and was collected by filtration, to obtain the title compound (328 mg, 0.69 mmol, 85%) as a white solid.
