Reaktionsschritte

A solution of 20.7 g (98 mmol) of methyl 2-methylamino-3-nitrobenzoate in 1200 mL of methanol was inerted with nitrogen. To this solution was added 5 g (2.3 mmol) 10% palladium on carbon (50% wet). The reaction was purged with hydrogen and stirred under balloon pressure hydrogen for 7 h. The catalyst was removed by filtration and the filtrate was concentrated in vacuo to give 17.5 g (99%) of the title compound.
