Ethanol → 2-Ethylamino-3-nitropyridine

Participants

Reaction Steps

2-Chloro-3-nitropyridine (20.00 g, 126 mmol) was added to ethylamine in ethanol (40 mL, 80 mmol) at room temperature and kept overnight. The solution was evaporated, the residue was diluted with 150 mL of EtOAc, washed with aqueous NaHCO3 and purified by column chromatography on silica gel (hexane/ethyl acetate 4/1) to give yellow solid (19.5 g, 92%).
