Procedure

A mixture of N-benzyl-N-methyl-2-nitropyridin-3-amine (2.6 g) and 10% Pd—C (0.569 g) in EtOH (50 mL) was hydrogenated under balloon pressure at room temperature over weekend. The catalyst was removed by filtration and the filtrate was concentrated in vacuo to give N3-methylpyridine-2,3-diamine (1.14 g) as pale yellow oil.
