Aminonicotinic acid benzyl ester derivative. This process is a process, (Wherein R 1 is a hydrogen atom or a C 1 -C 4 alkyl group, and M is an alkali metal), and a 2-aminonicotinic acid derivative represented by the formula (Wherein R 2 represents, for example, a hydrogen atom, a halogen atom, A represents, for example, a nitrogen atom, X represents a halogen atom, and Y represents, for example, an oxygen atom) In the presence of a catalyst or a tertiary amine in an aromatic hydrocarbon solvent. |
