Reaction Steps

4-Chloro-3-nitropyridin-2-amine (0.10 g, 0.58 mmol) was dissolved in dry acetonitrile (20 mL). To the stirred solution was then added N-chlorosuccinimide (0.094 g, 0.70 mmol), and the reaction mixture was heated at 80° C. for 1 h. Volatiles were removed in vacuo and the residue purified by silica column chromatography (elution with dichloromethane) to provide the title compound as a pale brown powder (0.125 g, 85%). 1H-NMR (500 MHz, DMSO-d6) 7.35 (s, 2H, NH2), 8.36 (s, 1H, 6-H).
