実験手順
4-Chloro-3-nitropyridine was prepared from 4-hydroxy-3-nitropyridine(25 g, 0.179M), phosphorus pentachloride(40 g, 0.192M) and 1 mL of phosphorous oxytrichloride. The mixture was heated at 120° for 1 hour. The reaction mixture was diluted with chlorform/ethanol mixture(9/1) and the precipitate was filtered to afford desired. (mp. 153-154° C.)
