Procedure

To a solution of 7-[4-(2-butoxyethoxy)phenyl]-N-[4-[hydroxy(1-oxidopyridin-2-yl)methyl]-3-trifluoromethylphenyl]1-(2,2,2-trifluoroacetyl)-2,3-dihydro-1-benzazepine-4-carboxamide (155 mg) in ethanol (10 ml) was added sodium borohydride (79 mg) and the mixture was stirred for 7 hours. To the mixture was added water and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine and dried over magnesium sulfate. The solvent was distilled off under reduced pressure, and recrystallized from diisopropyl ether-ethyl acetate, to give 7-[4-(2-butoxyethoxy)phenyl]-N-[4-[hydroxy(1-oxidopyridin-2-yl)methyl]-3-trifluoromethylphenyl]-2,3-dihydro-1-benzazepine-4-carboxamide (110 mg) as yellow crystals.
