反応手順

Concentrated hydrochloric acid (239 g) was added to 2-hydroxy-5-nitropyridine (40.0 g). The resulting slurry was heated to 53° C., and stirred until all the solids dissolved. To this was slowly added a solution of potassium chlorate (14.0 g) in water (250 g), while maintaining the temperature between 55° C. and 59° C. The resulting mixture was stirred at 58-62° C. for about 1 hour. The reaction was then cooled to room temperature, stirred for 12 hours and then filtered. After washing the wet cake with water, the product was dried in a vacuum oven. 1H NMR (400 MHz/DMSO-d6) δ 8.64 (d, J=2.9 Hz, 1H), 8.35 (d, J=2.9 Hz, 1H)
