Procedure

7-[4-(2-butoxyethoxy)phenyl]-1-isobutyl-N-[3-methoxy-4-[(3-pyridinylmethyl)sulfanyl]phenyl]-2,3-dihydro-1-benzazepine-4-carboxamide (0.39 g) was dissolved in methylene chloride (7.8 ml), a solution of m-chloroperbenzoic acid (152 mg) in methylene chloride (15.6 ml) was added to the mixture at −78° C., and the mixture was stirred for 15 minutes. The reaction mixture was added to an aqueous solution of saturated sodium thiosulfate, and extracted with ethyl acetate. The organic layer was washed with saturated brine, and dried over magnesium sulfate. The solvent was removed under reduced pressure, and the obtained residue was purified by silica gel column chromatography, to give 7-[4-(2-butoxyethoxy)phenyl]-1-isobutyl-N-[3-methoxy-4-[(3-pyridinylmethyl)sulfinyl]phenyl]-2,3-dihydro-1-benzazepine-4-carboxamide (Compound 240) (0.26 g).
