実験手順
A solution of m-chloroperbenzoic acid (80%; 0.76 g) in dichloromethane (12 ml) was added dropwise to a stirred solution of 4'-acetyl-2'-(2,4-difluorophenylthio)methanesulfonanilide (1.2 g) in dichloromethane (12 ml) at 5° to 10° C. The solution was stirred for 1 hour at the same temperature, washed with a saturated aqueous solution of sodium bicarbonate, dried over magnesium sulfate, and concentrated. The oily residue (0.9 g) was crystallized from ethanol to give crystals of 4'-acetyl-2'-(2,4-difluorophenylsulfinyl)methanesulfonanilide (0.73 g).
