摘要:
The present invention provides a process for producing the pyridine compound [d]: [wherein R3 and R4 are as defined below], which has an excellent herbicidal activity, by making a pyridine compound [a]: [wherein R1 represents a C1–C6 alkoxy group, R3 represents a halogen atom, cyano group or nitro group, and R4 represents a hydrogen atom or halogen atom] react with an α-diazoester compound [f]: N2CHCOR1[f] [wherein R1 is defined above] in the presence of an acid.
