Document Type and Number:
WIPO Patent Application WO/2016/114310
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a novel method for producing a nitro compound that is a precursor compound of a diamine compound, which is a raw material for a polyimide and/or polyamic acid used in a liquid crystal aligning agent or the like. Provided is a method for producing a diamine precursor compound represented by formula 3, by reacting, in accordance with reaction formula (1), a dinitro compound represented by formula 1 and a compound represented by formula 2 in the absence of a base while discharging, outside the reaction system as a gas, the hydrogen chloride that is generated. (In the formulae, R1 represents a monovalent organic group.)
