Reaction Steps
A mixture of 3-bromo-2-(2,4-difluorophenoxy)-5-nitropyridine (1.9 g, 5.9 mmol), ammonium chloride (637 mg, 11.8 mmol), and iron powder (1.65 g, 30 mmol) suspended in THF (10 mL), water (3 mL) and ethanol (10 mL) was heated to 90° C. using microwave irradiation (normal) for 5 h. The crude reaction mixture was filtered through a short plug of celite; the celite plug was washed with warm (50° C.) MeOH (˜50 mL). The resulting filtrate was concentrated in vacuo. The resulting residue was diluted with EtOAc (100 ml) and washed with saturated bicarbonate solution (aq), dried over anhydrous magnesium sulfate, filtered, and concentrated in vacuo to afford the title compound, (824 mg, 46%). LCMS (M+H)+=302.
