実験手順

To a solution of 7-[4-(2-butoxyethoxy)phenyl]-N-[4-(4-n-butyl-4H-1,2,4-triazol-3-ylmethylthio)phenyl]-1-isobutyl-2,3-dihydro-1H-benzazepine-4-carboxamide (1.01 g) in dichloromethane (20 ml) was added dropwise a solution of 3-chloroperbenzoic acid (70%, 0.55 g) in dichloromethane (10 ml) at −78° C., and the mixture was stirred for 1 hour at −78° C. 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 obtained residue was separated and purified by column chromatography (ethanol:ethyl acetate 1:9→1:4), and was recrystallized from ethyl acetate, to give 7-[4-(2-butoxyethoxy)phenyl]-N-[4-(4-n-butyl-4H-1,2,4-triazol-3-ylmethylsulfinyl)phenyl]-1-isobutyl-2,3-dihydro-1H-benzazepine-4-carboxamide (Compound 143) (794.5 mg) as yellow crystals.
