Versuchsvorschrift

To a solution of 7-[4-(2-butoxyethoxy)phenyl]-N-[4-[hydroxy(2-pyridyl)methyl]phenyl]-1,1-dioxo-2,3-dihydro-1-benzothiepine-4-carboxamide (Compound 150) (230 mg) in dichloromethane (10 ml) was added at 0° C. 3-chloroperbenzoic acid (70%, 0.12 g), and the mixture was stirred at room temperature for 24 hours. To the reaction mixture was added sodium thiosulfate solution, and the mixture was stirred for a few minutes and extracted with ethyl acetate. The organic layer was washed with sodium bicarbonate solution and saturated brine, dried with magnesium sulfate and concentrated under reduced pressure, and the residue was purified with column chromatography (ethanol/ethyl acetate=1:9→1:4) to give colorless crystals of 7-[4-(2-butoxyethoxy)phenyl]-N-[4-[hydroxy(1-oxidopyridin-2-yl)methyl]phenyl]-1,1-dioxo-2,3-dihydro-1-benzothiepine-4-carboxamide (Compound 151) (187 mg).
