Procedure

7-[4-(2-butoxyethoxy)phenyl]-N-[3-ethoxy-4-[hydroxy(4-methyl-1-oxidopyridin-2-yl)methyl]phenyl]-1-trifluoroacetyl-2,3-dihydro-1H-1-benzazepine-4-carboxamide (0.85 g) was dissolved in ethanol (200 ml), and to the solution, sodium borohydride (0.13 g) was added under ice-cooling and the mixture was stirred overnight at room temperature. The solvent was distilled off, and to the residue was added water, and the mixture was extracted with ethyl acetate. The organic layer was washed with water and saturated brine, and dried over anhydrous magnesium sulfate. The solvent was distilled off, to give 7-[4-(2-butoxyethoxy)phenyl]-N-[3-ethoxy-4-[hydroxy(4-methyl-1-oxidopyridin-2-yl)methyl]phenyl]-2,3-dihydro-1H-1-benzazepine-4-carboxamide (compound 11) (0.66 g) as yellow crystals.
