To a solution of N,N,4-trimethyl-5-nitropyridin-2-amine (15.7 g, 86.6 mmol) in ethanol (200 ml) was added 10% palladium on carbon (50% wet, 1.57 g), and the mixture was purged with hydrogen and stirred under balloon pressure hydrogen at room temperature for 2 days. The catalyst was removed by filtration, and the filtrate was concentrated in vacuo to give the title compound as a brown solid (15.7 g), which was used next reaction without purification.
