Procedure

7-[4-(2-butoxyethoxy)phenyl]-N-[3-chloro-4-[hydroxy(1-oxidopyridin-2-yl)methyl]phenyl]-1-trifluoroacetyl-2,3-dihydro-1H-1-benzazepine-4-carboxamide (0.24 g) was dissolved in ethanol (30 ml), and to the solution, sodium borohydride (0.065 g) was added under ice-cooling and the mixture was stirred at room temperature for 3 hours. 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 then, dried over anhydrous magnesium sulfate. The solvent was distilled off, to give 7-[4-(2-butoxyethoxy)phenyl]-N-[3-chloro-4-[hydroxy(1-oxidopyridin-2-yl)methyl]phenyl]-2,3-dihydro-1H-1-benzazepine-4-carboxamide (compound 5) (0.3 g) as yellow amorphous.
