Procedure

To a solution of 8-[4-(2-butoxyethoxy)phenyl]-1-isobutyl-N-[4-[[(4-propyl-4H-1,2,4-triazol-3-yl)methyl]thio]phenyl]-1,2,3,4-tetrahydro-1-benzazocine-5-carboxamide (0.70 g) in dichloromethane (20 ml) was added dropwise a solution of 3-chloro-perbenzoic acid (70%, 0.38 g) in dichloromethane (10 ml) and the mixture was stirred at −78° C. for 1 hour. To the reaction system was added an aqueous sodium thiosulfate solution, and the mixture was stirred at room temperature for 10 minutes. The mixture was extracted with ethyl acetate. The organic layer was washed with aqueous sodium bicarbonate solution and saturated brine, and was dried with magnesium sulfate. The resultant was concentrated under reduced pressure, the residue was separated and purified with column chromatography (basic silica gel, ethyl acetate→ethanol:ethyl acetate 1:19), followed by recrystallization (ethyl acetate diisopropyl ether) to give 8-[4-(2-butoxyethoxy)phenyl]-1-isobutyl-N-[4-[[(4-propyl-4H-1,2,4-triazol-3-yl)methyl]sulfinyl]phenyl]-1,2,3,4-tetrahydro-1-benzazocin-5-carboxamide (490.1 mg) as yellow crystals (Compound 47).
