5-Chloro-2-nitropyridine can be used as organic synthesis intermediate and pharmaceutical intermediate, mainly used in laboratory research and development process and chemical production process. | [Synthesis]
To concentrated H2SO4 (50 ml) was added 30 % H2O2 (25mL) at 0 ??C and a solution of 5-chloropyridin-2-amine (5.0 g, 39 mmol) in concentrated H2SO4 (20 mL) was added at 0 ??C. The mixture was stirred for 20 hours at room temperature. The mixture was poured into ice water under vigorously stirring and the resulting solid was filtered. The solid was recrystallized from ethanol to give 5-chloro-2-nitropyridine. 5-chloro-2-nitropyridine. MS m/z 159 (M+ 1)+. |
