发明名称 METHOD FOR PRODUCING 2-HALOGEN-PYRIDINE-CARBOXYLIC ACID AMIDES
摘要 The invention concerns a method for producing 2-halogen-pyridine-carboxylic acid amides of primary aromatic monoamines I which include, in ortho position relative to the amino group, a different hydrogen substituent, by reacting 2-halogen-pyridine-carboxylic acid chloride II with the aromatic monoamine I. The inventive method is characterized in that it consists in carrying out the reaction in a solvent mixture consisting of at least an organic solvent non-miscible with water, the mixture containing or not containing less than 10 mole %, relative to the 2-halogen-pyridine-carboxylic acid chloride II, a base different from I and II.
