To a solution of 7-[4-(2-butoxyethoxy)phenyl]-N-[4-(4-methyl-4H-1,2,4-triazol-3-ylthiomethyl)phenyl]-1-isobutyl-2,3-dihydro-1H-1-benzazepine-4-carboxamide (0.26 g) in dichloromethane (10 ml) was added a solution of 3-chloroperbenzoic acid (70%, 0.26 g) in dichloromethane (10 ml) at −78° C. and the mixture was stirred at −10 to −15° C. for 1.5 hours. To the reaction solution was added magnesium thiosulfate solution at room temperature and the mixture was stirred for several minutes. The mixture was extracted with ethyl acetate. The organic layer was washed with sodium bicarbonate solution and saturated brine, dried over magnesium sulfate and concentrated under reduced pressure. The obtained residue was separated and purified by column chromatography (ethanol:ethyl acetate 1:9→1:4) to give 7-[4-(2-butoxyethoxy)phenyl]-N-[4-(4-methyl-4H-1,2,4-triazol-3-ylsulfinylmethyl)phenyl]-1-isobutyl-2,3-dihydro-1H-1-benzazepine-4-carboxamide (Compound 118) (73.8 mg) as yellow crystals.
