Reaction Steps
A mixture of 6-bromo-3-methoxy-2-nitropyridine (14.4 g, 61.8 mmol), AcOH (200 mL) and Fe powder (14.0 g, 0.25 mol) was stirred at 90° C. for 1.5 h. After cooling to rt and dilution with EtOAc the mixture was filtered through celite and the filtrate concentrated in vacuo. Purification by flash chromatography eluting with DCM yielded the title compound (10.2 g, 50.2 mmol) as a white solid.
