| description | 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.
La présente invention concerne un procédé pour la préparation de dérivés de nitropyridine de formule (I) et ses sels et précurseurs tels que des amino pyridines halogénés; dans la formule (I) : R1 est choisi parmi un groupe amino, un groupe hydroxyle, un groupe acyle, un groupe alkylamino, un atome d'halogène, -NH - C (O) - R3; où R3 est un groupe ramifié ou linéaire ayant 1 à 6 atomes de carbone, ou un groupe cycloalkyle ayant 3 à 6 atomes de carbone; R2 est choisi parmi un groupe hydroxyle, un atome d'halogène, un groupe alcoxy. |
