Reaction Steps

2-Hydroxy-5-nitropyridine (50 g, 357 mmol) and N-chlorosuccinimide (55 g, 410 mmol) were suspended in anhydrous DMF (150 mL). The suspension was stirred at room temperature for 18 hours. The resulting homogeneous reaction mixture was diluted by the slow addition of water (750 mL), which resulted in a pale yellow precipitate. The solids were isolated via filtration and dried under high vacuum to provide 3-chloro-5-nitro-2-hydroxypyridine (59 g, 95% yield).
