To a solution of 2-(4-iodophenoxy)-1-(3-methoxyphenyl)ethanol (215 mg) in dimethylformamide (2 ml), 0.072 ml of iodomethane and 46 mg of sodium hydride were added under ice-cooling, and the reaction solution was stirred at room temperature for 30 minutes. To the reaction solution was added an aqueous saturated ammonium chloride solution, and the mixture was extracted with ethyl acetate. The combined organic layers were washed with a saturated saline solution and then dried over anhydrous sodium sulfate. The solvent was distilled off under reduced pressure, and the residue obtained was purified by silica gel column chromatography (eluent: hexane/ethyl acetate (98:2-50/50)) to afford the title compound as a colorless oil.
