In 1,2-dichloroethane (5 ml) were dissolved methyl 7-[4-(2-butoxyethoxy)phenyl]-2,3-dihydro-1H-1-benzazepine-4-carboxylate (0.3 g) and cyclohexanecarboaldehyde (0.43 g). To the solution was added sodium triacetoxyborohydride (0.43 g), and the mixture was stirred under nitrogen atmosphere at room temperature for 3.5 hours, poured into water, neutralized with sodium hydrogen carbonate solution and extracted with ethyl acetate. The organic layer was washed with water and saturated brine and dried with anhydrous magnesium sulfate. The solvent was evaporated to give methyl 7-[4-(2-butoxyethoxy)phenyl]-1-cyclohexylmethyl-2,3-dihydro-1H-1-benzazepine-4-carboxylate (0.37 g) as pale yellow oil.
