Procedure
To a mixture of N-(7-ethyl-3-(4-isopropylphenyl)-4,6-dimethyl-2,3-dihydro-1-benzothien-5-yl)-3,3-dimethylbutanamide (225 mg, 0.512 mmol) obtained in Example 164 and sodium hydrogen carbonate (65 mg, 1.01 mmol) in dichloromethane (10 mL) was added m-chloroperbenzoic acid (124 mg, 0.716 mmol) at 0° C. and the resulting mixture was stirred at room temperature for two hours. To reaction solution was added an aqueous sodium hydrogensulfate solution, the organic layer separated, and the aqueous layer was extracted with dichloromethane. The combined organic layers were washed with water and saturated brine, dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (hexane:ethyl acetate=3:1) to obtain 50 mg (yield: 22%) of the title compound. Melting point: 195-196° C. (ethyl acetate-hexane).
