To a solution of N-(4-(cyclohexylthiomethyl)-phenyl)-7-(4-methylphenyl)-2,3-dihydro-1-benzoxepine-4-carboxamide (0.19g) in dichloromethane (5ml) was added 70% m-chloroperbenzoic acid (0.097g) under ice-cooling, and the mixture was stirred for 10 minutes. To the mixture was added sodium thiosulfate solution, and the mixture was extracted with ethyl acetate. The organic layer was washed with water and saturated sodium chloride solution, and dried with anhydrous magnesium sulfate. Under reduced pressure, the solvent was evaporated, and the residue was purified with silica gel column (methanol/dichloromethane) to give crude crystals, which were recrystallized from ethanol to give N-(4-(cyclohexylsulfinylmethyl)-phenyl)-7-(4-methylphenyl)-2,3-dihydro-1-benzoxepine-4-carboxamide (Compound 106) (0.048g) as colorless crystals.
