Procedure

To a solution of 7-[4-(2-butoxyethoxy)phenyl]-N-[4-[[[1-[4-(methylamino)-4-oxobutyl]-1H-imidazol-2-yl]methyl]thio]phenyl]-1-isobutyl-2,3-dihydro-1H-1-benzazepine-4-carboxamide (400 mg) in dichloromethane (10 ml) was added a solution of 3-chloroperbenzoic acid (70%, 0.2 g) in dichloromethane (15 ml) at −78° C. The mixture was stirred for 1.5 hours at −78° C., an aqueous solution of sodium thiosulfate was added to the mixture, and the mixture was stirred at room temperature for 10 minutes. The mixture was extracted with ethyl acetate, washed with an aqueous solution of sodium bicarbonate and saturated brine, and dried over magnesium sulfate, and concentrated under reduced pressure. The obtained residue was separated and purified by column chromatography (basic silica gel, ethanol:ethyl acetatel:19), and was further recrystallized from ethyl acetate-diisopropyl ether to give 7-[4-(2-butoxyethoxy)phenyl]-N-[4-[[[1-[4-(methylamino)-4-oxobutyl]-1H-imidazol-2-yl]methyl]sulfinyl]phenyl]-1-isobutyl-2,3-dihydro-1H-1-benzazepine-4-carboxamide (Compound 424) (342.8 mg) as yellow crystals.
