반응 단계

A mixture of 1-acetyl-4-(4-nitrophenyl)piperazine (1.8 g, 7.2 mmol) (from Step A above) and 10% palladium-on-charcoal in ethanol (50 mL) was hydrogenated at room temperature and atmospheric pressure overnight. The catalyst was filtered off and the filter cake washed thoroughly with ethanol. The mixture was evaporated under reduced pressure to give 1-acetyl-4-(4-amino-phenyl)piperazine (1.0 g, 63%) as an off-white solid.
