METHOD FOR PRODUCING NITRO COMPOUND

WIPO Patent Application WO/2015/159905

A1

A compound represented by formula (1) (wherein X represents a chlorine atom, a bromine atom or an iodine atom) can be produced by: a step wherein a compound represented by formula (2) (wherein R1a represents an alkyl group having 1-6 carbon atoms or the like, and each of R1b and R1c represents a hydrogen atom or the like) is reacted with a compound represented by formula (3) (wherein each of R2 and R3 independently represents an alkyl group having 1-3 carbon atoms or the like, and each of R6 and R7 independently represents an alkoxy group having 1-3 carbon atoms or the like), thereby obtaining a compound represented by formula (4); a step wherein a compound represented by formula (4) is oxidized; a step wherein the product in the oxidation step is reduced; and a step wherein the product by the reduction reaction is halogenated.
