Versuchsvorschrift

To a solution of ethyl 4-(2-(((4-(((8-(4-(2-butoxyethoxy)phenyl)-1-isobutyl-1,2,3,4-tetrahydro-1-benzazocine-5-yl)carbonyl)amino)phenyl)sulfanyl)methyl)-imidazol-1-yl)butanoate (400 mg) in dichloromethane (10 ml) was added dropwise a 70% solution of 3-chloroperbenzoic acid (144 mg) in dichloromethane (10 ml) at −78° C. As such, the mixture was stirred for 1 hour. Then, dry ice-acetone bath was removed and an aqueous sodium thiosulfate solution was added with vigorous stirring. After stirring the mixture at room temperature for 30 minutes, water was added and the mixture was extracted with ethyl acetate. The organic layer was washed with aqueous saturated sodium bicarbonate solution and saturated brine, and was dried with magnesium sulfate. The solvent was distilled off under reduced pressure, and the resulting residue was separated and purified with basic silica gel column chromatography (hexane:ethyl acetate=1:1→ethyl acetate), and recrystallized from hexane-ethyl acetate to give ethyl 4-(2-(((4-(((8-(4-(2-butoxyethoxy)phenyl)-1-isobutyl-1,2,3,4-tetrahydro-1-benzoazocine-5-yl)carbonyl)amino)phenyl)sulfinyl)methyl)imidazol-1-yl)butanoate (317 mg) as yellow crystals (Compound 54).
