Document Type and Number:
WIPO Patent Application WO/2018/084120
Kind Code:
A1
Abstract:
A benzoic acid derivative and a dehydration-condensation agent, each of which is represented by formula (I) or (II). In formulae (I) and (II), R1 represents a haloalkyl group, a halogen atom or a cyano group; and R2, R3 and R4 independently represent a hydrogen atom, a haloalkyl group, a halogen atom or a cyano group. In formula (I), two R1's, two R2's, two R3's or two R4's may be the same as or different from each other.
