Reaction Steps
4Methoxy-3-nitropyridine hydrochloride (11.2 g, 58.9 mmol) in ethanol (75 ml) was treated with a 70% solution of ethylamine in water (64 ml) and heated under reflux for 2 hours. After cooling to room temperature, the solvent was removed in vacuo and the residue dissolved in ethyl acetate and water. The mixture was extracted (×3) with ethyl acetate, washed with water and saturated aqueous sodium chloride solution before drying over magnesium sulfate. Evaporation of the solvent afforded the title compound (11.7 g, 96%).
