Versuchsvorschrift

To a solution of 7-[4-(2-butoxyethoxy)phenyl]-N-[4-[(S)-hydroxy(1-oxidopyridin-2-yl)methyl]phenyl]-2,3-dihydro-1H-1-benzazepine-4-carboxamide (120 mg) and propionaldehyde (0.15 ml) in 1,2-dichloroethane (10 ml) was added sodium triacetoxyborohydride (0.13 g) at room temperature, and the mixture was stirred for 20 hours. To the reaction solution 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 removed under reduced pressure, and the obtained residue was purified by column chromatography (ethanol:ethyl acetate 1:2), to give 7-[4-(2-butoxyethoxy)phenyl]-N-[4-[(S)-hydroxy(1-oxidopyridin-2-yl)methyl]phenyl]-1-propyl-2,3-dihydro-1H-1-benzazepine-4-carboxamide (Compound 83) (105.4 mg) as yellow crystals.
