METHOD FOR PRODUCING NITRO COMPOUND

摘要

A nitro compound represented by formula (1) which is a raw material for producing a compound represented by formula (7) can be produced by reacting at least one type selected from the group consisting of a compound represented by formula (2), a compound represented by formula (3), and a compound represented by formula (3′) with a compound represented by formula (4). [In the formula, R1, R2, R3, and R4 are each independently a hydrogen atom, etc., X1 and X2 are each independently a chlorine atom, etc., R6, R7, R8, and R9 are a hydrogen atom, etc., provided that X1, X2, R6, R7, R8, and R9 are not all the same, X3, X4, and X5 are a halogen atom, R10 is a nitro group, etc., R5 is an alkyl group having 1 to 12 carbon atoms, etc., and M is an alkali metal atom.];
