m-Chloroperbenzoic acid → HCID 57736422, compound

Participants

Reaction Steps

3-Chloroperbenzoic acid (66 mg, 0.25 mmol) was added to a solution of 5-[[(4-chlorophenyl)sulfinyl](2,5-difluorophenyl)methyl]-4-methylpyridine-2-carboxamide (105 mg, 0.25 mmol) in methylene chloride (5 ml) at 0° C. After stirring for 5 days at room temperature, the reaction mixture was washed with 1 N aqueous sodium hydroxide. The organic layer was dried over anhydrous sodium sulfate and filtered, then the filtrate was concentrated under reduced pressure, and the resulting residue was subjected to preparative thin-layer chromatography (developed with methylene chloride:methanol=40:1, and eluted with methylene chloride:methanol=4:1). The obtained fraction was concentrated under reduced pressure, and the resulting residue was washed with a mixed solvent of ethanol and diethyl ether and collected by filtration, thus to obtain the title compound (56 mg, 0.13 mmol, 51%) as a white solid.
