Reaction Conditions

Reaction Steps

To a warm (50° C.) solution of 2-hydroxy-5-nitro-pyridine (17 g, 121 mmol) in concentrated HCl (80 mL) was added dropwise NaClO3 (4.5 g, 42.5 mmol) in water (70 mL), keeping the internal temperature below 60° C. The reaction mixture was stirred for 15 min and then cooled to 0° C. The resulting precipitate was collected by vacuum filtration and dried to provide 19.7 g of the title compound. ESI-MS: 173 [M−H]− (LC-MS 2); Rf=0.55 (hexane/EtOAc, 1:1).
