Procedure

7-[4-(2-butoxyethoxy)phenyl]-N-[4-[hydroxy(1-oxidopyridin-2-yl)methyl]-3-methoxyphenyl]-2,3-dihydro-1H-1-benzazepine-4-carboxamide (0.3 g) and isobutylaldehyde (0.22 ml) were dissolved in 1,2-dichloroethane (15 ml), and to the solution, triacetoxy sodium borohydride (0.31 g) was added under ice-cooling and the mixture was stirred overnight at room temperature. The mixture was poured into water, neutralized with solution of sodium bicarbonate, and 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-[4-[hydroxy(1-oxidopyridin-2-yl)methyl]-3-methoxyphenyl]-1-isobutyl-2,3-dihydro-1H-1-benzazepine-4-carboxamide (compound 4) (0.3 g) as yellow amorphous.
