Reaction Steps

A solution of sodium methoxide (0.84 g, 16.6 mmol) in methanol (4 mL) was added dropwise to a solution of 2,5-dichloro-3-nitropyridine (1.00 g, 5.2 mmol) in methanol (10 mL) and the mixture was stirred and heated to reflux. After 7 hours, the mixture was cooled and diluted with water and the precipitate was filtered and washed with water to give the title compound (0.95 g, 97%) as a white solid.
