Abstract
2-chloro-4-aminopyridine was synthesized from 2-chloropyridine through N-oxidation,green nitration and reduction with one pot method.The optimum processing conditions in the nitrifying process were established as reacting at 120 ℃ for 3 h with concentrated nitric acid and potassium nitrate as nitrating agent.The yield was 81.3% under these conditions.The character of the synthesized product was analyzed by IR,melting point test,elemental analysis and MS;and the results proved that the product was with correct structure.
