반응 단계

A 1.421 g portion of 6-(4-nitrobenzoyl)-2,3-dimethyl-3,4,5,6-tetrahydroimidazo[4,5-d][1]benzazepine was dissolved in 50 ml of methyl alcohol, and the solution was mixed with 300 mg of palladium-carbon and subjected to hydrogenation under normal pressure. After completion of the hydrogen absorption, the reaction mixture was subjected to filtration and the resulting filtrate was concentrated to obtain 571 mg of 6-(4-aminobenzoyl)-2,3-dimethyl-3,4,5,6-tetrahydroimidazo[4,5-d][1]benzazepine.
