Reaction Steps
A solution of 2-chloro-6-methoxy-3-nitropyridine (25.3 g, 0.134 mol) and a concentrated aqueous ammonia solution (70 ml) in N,N-dimethylformamide (200 ml) was stirred at 70° C. for 4 hours and 15 minutes. The reaction mixture was cooled to room temperature and then diluted with water. The resulted precipitate was collected by filtration to yield the title compound (16.8 g, 99.2 mmol, 74.0%) as a yellow solid.
