Title:
METHOD FOR PRODUCING PYRIDINE COMPOUND
Document Type and Number:
WIPO Patent Application WO/2018/194077
Kind Code:
A1
Abstract:
The present invention provides a method for producing a compound represented by formula (4), which is useful as, for example, an agrochemical or an intermediate for agrochemical production, the method including the step of reacting a compound represented by formula (2) with an organic oxidant.
[In the formulae, Q represents a pyridyl group, etc.; R1 represents a C1-6 alkyl group optionally having one or more halogen atoms; R2 represents, for example, a C1-6 alkyl group optionally having one or more halogen atoms; R3, R4, and R5 each represent a hydrogen atom, etc.; and n is 0, etc.]
