Versuchsvorschrift

To a solution of 7-[4-(2-butoxyethoxy)phenyl]-1-formyl-N-[4-[(R)-hydroxy(2-pyridyl)methyl]phenyl]-2,3-dihydro-1H-1-benzazepine-4-carboxamide (130 mg) in dichloromethane (20 ml) was added 3-chloroperbenzoic acid (70%, 65 mg) at 0° C., and the mixture was stirred at room temperature for 18 hours. To the-reaction solution was added sodium thiosulfate solution, and the mixture was stirred for several minutes, and extracted with ethyl acetate. 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 purified by column chromatography (ethanol:ethyl acetate 1:4) and recrystallized from ethyl acetate-diisopropylether to give 7-[4-(2-butoxyethoxy)phenyl]-1-formyl-N-[4-[(R)-hydroxy(1-oxidopyridin-2-yl)methyl]phenyl]-2,3-dihydro-1H-1-benzazepine-4-carboxamide (Compound 78) (68.2 mg) as pale yellow crystals.
