실험 절차
In ethanol (500 ml) is dispersed 10% Pd-C (5 g), and thereto is added 5-dimethylamino-1-(4-nitrobenzoyl)-2,3,4,5-tetrahydro-1H-benzazepine (64.1 g), and the mixture is subjected to catalytic reduction at ordinary room temperature under atmospheric pressure. After reduction, 10% Pd-C is removed by filtration, and the filtrate is concentrated under reduced pressure to give 5-dimethylamino-1-(4-aminobenzoyl)-2,3,4,5-tetrahydro-1H-benzazepine (56.1 g) as white powder, mp. 120°-122° C.
