Procedure

To a solution of ethyl 4-[2-[[[4-[[[7-[4-(2-butoxyethoxy)phenyl]-1-isobutyl-2,3-dihydro-1H-1-benzazepin-4-yl]carbonyl]amino]phenyl]thio]methyl]-1H-imidazol-1-yl]butanoate (1.0 g) in dichloromethane (10 ml) was added dropwise a solution of 3-chloroperbenzoic acid (70%, 0.50 g) in dichloromethane (10 ml) at −78° C. The mixture was stirred for 1 hour 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, and 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 (basic silica gel, ethyl acetate), to give ethyl 4-[2-[[[4-[[[7-[4-(2-butoxyethoxy)phenyl]-1-isobutyl-2,3-dihydro-1H-1-benzazepine-4-yl]carbonyl]amino]phenyl]sulfinyl]methyl]-1H-imidazol-1-yl]butanoate (Preparation of Compound 414) (911 mg) as yellow crystals.
