METHOD FOR PRODUCING CONDENSED HETEROCYCLIC COMPOUND

WIPO Patent Application WO/2019/009387

A1

The compound represented by general formula (1) (wherein R1 and R2 represent a halo (C1-C6) alkyl group or a halo (C1-C6) alkylthio group) is useful as an agricultural pesticide, and there is a strong demand for the development of an industrially advantageous method of synthesizing the same in a short process. Provided is a method for producing the compound represented by general formula (1), the method including a step for producing a compound represented by general formula (2) through a coupling reaction of a compound represented by general formula (4) (wherein R1 is as defined previously) and a compound represented by general formula (3) (wherein R2 is as defined previously, X represents a halogen atom, and Y represents a halogen atom or a halo (C1-C6) alkylthio group).
