실험 절차

3-Nitro-2,4,6-trimethylpyridine (14.89 g, 89.70 mmol) in methanol (250 ml) containing 10% palladium/carbon (1.5 g) was hydrogenated at 55 psi for 2 hours. The reaction mixture was filtered through wet celite, and the celite filter rinsed with methanol (5×30 ml). The filtrate was concentrated in vacuo to dryness and the residue purified by chromatography (silica gel; methylene chloride/methanol, 95/5) to 3-amino-2,4,6-trimethylpyridine (12.42 g, 100%) as a viscous oil.
