2-Chloro-3-nitropyridine Chemical Properties,Usage,Production
Chemical Properties
yellow crystalline powder
Uses
2-Chloro-3-nitropyridine is often used as a pharmaceutical intermediate.
Reactions
2-Chloro-3-nitropyridine is a nucleophilic compound that reacts with amines to form substituted amines.
Synthesis
59290-85-6
5470-18-8
General procedure for the synthesis of 2-chloro-3-nitropyridine from 3-nitropyridine-2-carboxylic acid: accurately weigh 3-nitropyridine-2-carboxylic acid (50.4 mg, 0.3 mmol), sodium carbonate (64.0 mg, 0.6 mmol), sodium chloride (17.6 mg, 0.3 mmol) and tert-butyl hypochlorite (32 μL, 0.3 mmol) in a 25 mL Schlenk reaction flask. Subsequently, dichloromethane (3 mL) was added as a solvent and the reaction mixture was placed in an oil bath at 25 °C for 20 hours. After completion of the reaction, the solvent was removed by distillation under reduced pressure. The crude product was purified by silica gel column chromatography using petroleum ether/ethyl acetate as eluent to give 2-chloro-3-nitropyridine in 58% yield.
Purification Methods
It forms needles from H2O. Purify it by continuous sublimation over a period of 2 weeks at 50-60o/0.1mm [Barlin J Chem Soc 2150 1964]. The N-oxide has m 100o(from CH2Cl2/Et2O). [Taylor & Driscoll J Org Chem 25 1716 1960, Ochiai & Kaneko Chem Pharm Bull Jpn 8 28 1960, Beilstein 20/5 V 451.]
