Participants

Reaction Steps

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 (250 mg, 0.590 mmol) in dichloromethane (20 mL) was added m-chloroperbenzoic acid (283 mg, 1.65 mmol) at 0° C. and the resulting mixture was stirred at room temperature for 2 hours. To the reaction solution was added an aqueous sodium hydrogensulfite solution, the organic layer was 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=4:1) to obtain 74 mg (yield: 28%) of the title compound. Amorphous powder.
