Procedure

To a mixture of N-(7-acetyl-3-(4-isopropylphenyl)-4,6-dimethyl-2,3-dihydro-1-benzothien-5-yl)-3,3-dimethylbutanamide (960 mg, 2.19 mmol) obtained in Example 166 and sodium hydrogen carbonate (276 mg, 3.29 mmol) in dichloromethane (20 mL) was added m-chloroperbenzoic acid (530 mg, 3.07 mmol) at 0° C. and the resulting mixture was stirred at room temperature for two hours. To reaction solution was added an aqueous sodium hydrogensulfite 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 (ethyl acetate) to obtain 123 mg (yield: 12%) of the title compound as a low polarity isomer. Melting point: 214-216° C. (hexane-ethyl acetate).
