5-dimethylamino-1-(4-nitrobenzoyl)-2,3,4,5-tetrahydro-1H-benzazepine → 5-dimethylamino-1-(4-aminobenzoyl)-2,3,4,5-tetrahydro-1H-benzazepine

Participants

Reaction Steps

5 g of 10% palladium-carbon was dispersed in 500 ml of ethanol. Thereto was added 64.1 g of 5-dimethylamino-1-(4-nitrobenzoyl)-2,3,4,5-tetrahydro-1H-benzoazepine. The mixture was subjected to catalytic reduction at normal temperature at normal pressure. After the reduction, 10% palladium-carbon was removed by filtration. The filtrate was concentrated under reduced pressure to obtain 56.1 g of 5-dimethylamino-1-(4-aminobenzoyl)-2,3,4,5-tetrahydro-1H-benzoazepine.
