Procedure

7-[4-(2-butoxyethoxy)phenyl]-N-[4-[hydroxy(pyridin-2-yl)methyl]-3-methoxyphenyl]-1-trifluoroacetyl-2,3-dihydro-1H-1-benzazepine-4-carboxamide (0.55 g) was dissolved in dichloromethane (25 ml), and to the solution was added 3-chloroperbenzoic acid (0.26 g) under ice-cooling and the mixture was stirred overnight at room temperature. An aqueous solution of sodium thiosulfate was added to the mixture, and the mixture was concentrated and extracted with ethyl acetate. The organic layer was washed with sodium bicarbonate solution, water and saturated brine, and dried over anhydrous magnesium sulfate and the solvent was distilled off, to give 7-[4-(2-butoxyethoxy)phenyl]-N-[4-[hydroxy(1-oxidopyridin-2-yl)methyl]-3-methoxyphenyl]-1-trifluoroacetyl-2,3-dihydro-1H-1-benzazepine-4-carboxamide (0.44 g) as colorless amorphous.
