To a solution of 7-[4-(2-butoxyethoxy)phenyl]-N-[4-[(S)-hydroxy(1-oxidopyridin-2-yl)methyl]phenyl]-2,3-dihydro-1-trifluoroacetyl-1H-1-benzazepine-4-carboxamide (180 mg) in ethanol (30 ml) was added sodium borohydride (10.0 mg) at room temperature and stirred for 2 hours. To the reaction solution was further added sodium borohydride (10.0 mg), and the mixture was stirred for 2 hours. To the reaction solution was added water, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, dried over magnesium sulfate and concentrated under reduced pressure. The obtained residue was purified by column chromatography (ethanol:ethyl acetate 1:2) to give 7-[4-(2-butoxyethoxy)phenyl]-N-[4-[(S)-hydroxy(1-oxidopyridin-2-yl)methyl]phenyl]-2,3-dihydro-1H-1-benzazepine-4-carboxamide (Compound 82) (141.4 mg) as yellow amorphous.
