摘要

An imidazolidine derivative having the formula (I) or its salt: (I) wherein X is an alkyl group which may be substituted, an alkenyl group which may be substituted, an alkynyl group which may be substituted, a group (in which each of R1, R2, R3 and R4 is independently a hydrogen atom or an alkyl group, R5 is an alkyl group which may be substituted with a halogen atom, a cycloalkyl group which may be substituted or a phenyl group which may be substituted, W is an oxygen atom or a sulfur atom, and each of k, ?, m and n is independently 0 or 1, provided that (a) case where all of k, ? and m are 0 at the same time and (b) case where m and n are 0 at the same time and R5 is an alkyl group which may be substituted with a halogen atom, are excluded), or a group (in which each of R5 and R7 is independently a hydrogen atom or an alkyl group, each of R8 and R9 is independently an alkyl group, R10 is an alkyl group which may be substituted, an aryl group which may be substituted, a pyridyl group which may be substituted, an alkenyl group which may be substituted with a halogen atom or an alkynyl group which may be substituted with a halogen atom); Y is a 6-chloro-3-pyridyl group or a 2-chloro-5-thiazolyl group; Z is a hydrogen atom, an alkyl group or an acyl group; and j is an integer of from 0 to 2.
