Abstract

Process for the preparation of the 2- (2-methyl-3-nitro-phenylamino) nicotinic acid of formula ** (See formula) ** characterized in that a nicotinic acid derivative of general formula II is condensed: ** (See formula) ** wherein X means a fluorine, chlorine, bromine or iodine atom, or an amino radical, with a compound of general formula III: ** (See formula) ** wherein Y means an amino radical, when X means a fluorine, chlorine, bromine or iodine atom, or Y means a fluorine, chlorine, bromine or iodine atom, when X means an amino radical, in a solvent or mixture of solvents that are inert under the conditions of the reaction, in the presence of a catalyst and a basic condensation agent.
