Procedure

Sodium hydride (32 mg, 60% by weight, 0.8 mmol) was suspended in THF (10 ml) and a THF (5 ml) solution of N-{3-isobutyl-4-[1-methoxy-2,2,2-trifluoro-1-(trifluoromethyl)ethyl]pheny}-3-methylpyrazine-2-carboxamide (300 mg, 0.67 mmol) was added dropwise thereto. The reaction solution was stirred at room temperature for 30 minutes, and was added with a THF (2 ml) solution of chloromethyl ethyl ether (76 mg, 0.8 mmol) and stirred for 5 hours. The reaction solution was poured into a diluted HCl solution, followed by extracting with ethyl acetate, and washing with water. The solution was dried over magnesium sulfate, and concentrated under reduced pressure, and then the residue was purified by using silica gel chromatography (hexane:ethyl acetate=3:1) to obtain 0.24 g of the desired compound.
