Procedure
3-Methoxy-2-methyl-6-nitropyridine (0.317 g.) in 20 ml. of methanol, was hydrogenated over 0.1 g. of 5% palladium-on-carbon catalyst. The catalyst was removed by filtration and the filtrate was concentrated to dryness to give 6-amino-3-methoxy-2-methylpyridine, which was used directly in the next step.
