Reaktionsschritte

N-Acetyl-2,6-dimethyl-3-nitroaniline (30.6 g; 0.15 mole) was dissolved in a mixture of methanol (100 ml), ethanol (50 ml) and acetic acid (100 ml). To the resulting solution was added 2.0 g of 10% palladium carbon and the mixture was stirred in a stream of hydrogen at room temperature for 26 hours. The catalyst was filtered off, the filtrate was concentrated under reduced pressure, and the residue was recrystallized from ethanol-ether to give 22.0 g (84%) of the title object compound as crystals, m.p. 195°-197° C.
