Procedure

To a solution of 7—(4-methylphenyl)-N-(4—(phenylthiomethyl)phenyl)-2,3-dihydro-1-benzoxepine-4-carboxamide (0.1 g) in dichloromethane (30 ml) was added 70% m-chloroperbenzoic acid (0.046 g) at the temperature ranging from −20 to −10° C., and the mixture was stirred for 30 minutes. To the mixture was added sodium thiosulfate solution, and the mixture was concentrated and extracted with ethyl acetate. The organic layer was washed with sodium hydrogen carbonate solution, water and saturated sodium chloride solution, and dried with anhydrous magnesium sulfate. Under reduced pressure, the solvent was evaporated to give crude crystals, which were recrystallized from ethyl acetate-hexane to give 7—(4-methylphenyl)-N-(4—(phenylsulfinylmethyl)phenyl)-2,3-dihydro-1-benzoxepine-4-carboxamide (Compound 108) (0.11 g) as colorless crystals.
