PROCESS FOR PREPARATION OF NITROPYRIDINE DERIVATIVES

摘要

Disclosed here is a process for the preparation of nitropyridine derivatives of Formula (I) and its salt and precursors such as halogenated amino pyridines; Wherein; R1 is selected from amino group, hydroxyl group, acyl group, alkyl amino group, halogen atom, -NH - C (O) - R3; Where R3 is branched or linear alkyl group having 1 - 6 carbon atoms, or cycloalkyl group having 3 - 6 carbon atoms; R2 is selected from hydroxyl group, halogen atom, alkoxy group,
