実験手順
To a solution of methyl 3-[(4-chloro-2-{[(4-chloro-2-fluorophenyl)sulfonyl]amino}phenyl)sulfanyl]propanoate (173 mg, 0.39 mmol) in CH2Cl2 (5 ml) was added mCPBA (142 mg, ˜0.59 mmol). The reaction was stirred at room temperature for 1 hour, and was directly loaded on Celite, purified by flash column chromatography on silica gel (30-70% EtOAc in hexane) to yield the title compound (40 mg, 22%).
