Procedure

To a solution of 3-methoxy-6-methyl-2-nitropyridine (3.85 g) in ethanol (91.6 ml) was added 10% palladium-carbon (50% wet, 0.96 g), and the mixture was stirred under hydrogen atmosphere for 2 hours. The catalyst was filtered off, and the filtrate was concentrated to dryness. The residue was recrystallized from ethyl acetate/hexane to give the title compound (2.89 g).
