Procedure

To a solution of 7-[4-(2-butoxyethoxy)phenyl]-N-[4-(4-methyl-4H-1,2,4-triazol-3-ylmethylthio)phenyl]-1-propyl-2,3-dihydro-1H-1-benzazepine-4-carboxamide (0.70 mg) in dichloromethane (20 ml) was added dropwise a solution of 3-chloroperbenzoic acid (70%, 0.41 g) in dichloromethane (5 ml) at −78° C. The mixture was stirred for 1 hour at −78° C., and to the reaction solution was added sodium thiosulfate solution at room temperature and the mixture was stirred for several 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 residue was separated and purified by basic silica gel column chromatography (ethanol:ethyl acetate ˜1:9), and was further recrystalized from ethyl acetate-hexane, to give 7-[4-(2-butoxyethoxy)phenyl]-N-[4-(4-methyl-4H-1,2,4-triazol-3-ylmethylsulfinyl)phenyl]-1-propyl-2,3-dihydro-1H-1-benzazepine-4-carboxamide (Compound 133) (613.2 mg) as yellow crystals.
