m-Chloroperbenzoic acid → HCID 59750823, compound

Participants

Reaction Steps

The 2-[3-[(4-chlorophenyl)sulfonyl]-3-(2,5-difluorophenyl)propylthio]ethanol (65 mg, 0.16 mmol) obtained in Example 250 was dissolved in dichloromethane (5 ml), followed by the addition of 3-chloroperbenzoic acid (33 mg, 0.19 mmol) under ice cooling. The resulting mixture was stirred at room temperature for 14 hours. The residue obtained by concentrating the reaction mixture under reduced pressure was subjected to flash silica gel chromatography, and the fraction obtained from the dichloromethane:methanol=30:1 eluate was concentrated under reduced pressure to give a white solid. The white solid was washed with diethyl ether, whereby the title, compound (50 mg, 0.12 mmol, 74%) was obtained as a white powder.
