実験手順
To a solution of 7-bromo-2,3,4,5-tetrahydro-1H-1-benzazepine-5-one (5.0 g), propionaldehyde (15 ml) and acetic acid (4.7 ml) in 1,2-dichloroethane (250 ml) was added sodium triacetoxyborohydride (22.0 g) at room temperature, and the mixture was stirred for 6 hours. To the reaction system was added water, and the mixture was extracted with ethyl acetate. The organic layer was washed with an aqueous solution of sodium hydrogen carbonate and saturated brine, and dried with magnesium sulfate. After concentration under reduced pressure, the residue was separated and purified with column chromatography (ethyl acetate:hexane=1:4) to give 7-bromo-1-propyl-2,3,4,5-tetrahydro-1H-1-benzazepine-5-one (5.89 g) as yellow oil.
