Versuchsvorschrift

To a solution of 7-[4-(2-butoxyethoxy)phenyl]-1-isobutyl-N-[4-[[(1-methylimidazol-2-yl)methyl]sulfanyl]phenyl]-2,3-dihydro-1-benzazepine-4-carboxamide (200 mg) in dichloromethane (20 ml) was added dropwise 70% solution of 3-chloroperbenzoic acid (116 mg) in dichloromethane (20 ml) at −78° C. After finishing the dropping, an aqueous solution of sodium thiosulfate was added to the mixture, and the mixture was allowed to be at room temperature, stirred for 30 minutes, and extracted with ethyl acetate. The organic layer was washed with an aqueous solution of saturated sodium bicarbonate, and saturated brine, and dried over magnesium sulfate. The solvent was distilled off under reduced pressure. The obtained residue was separated and purified by silica gel column chromatography (methanol:ethyl acetate=1:8), and was recrystallized from hexane-ethyl acetate, to give 7-[4-(2-butoxyethoxy)phenyl]-1-isobutyl-N-[4-[[(1-methylimidazol-2-yl)methyl]sulfinyl]phenyl]-2,3-dihydro-1-benzazepine-4-carboxamide (118 mg) (Compound 323) as yellow crystals, and was recrystallized from hexane-ethyl acetate, to give 7-[4-(2-butoxyethoxy)phenyl]-1-isobutyl-N-[4-[[(1-methylimidazol-2-yl)methyl]sulfonyl]phenyl]-2,3-dihydro-1-benzazepine-4-carboxamide (33.5 mg) (Compound 324) as yellow crystals.
