In the case that a selectively monoacylated phenylenediamine derivative which is useful as any of medicines, agricultural chemicals, animal drugs and the intermediates of chemicals is prepared by reacting a benzoic acid derivative with a phenylenediamine derivative, the benzoic acid derivative is converted into a benzoyl imidazole derivative and this benzoyl imidazole derivative is then reaction with the phenylenediamine derivative, whereby the improvement of a preparation efficiency and the high selectivity of the monoacylation can be achieved, the steps of protection and deprotection being omitted.
在一个选择性地单酰化的
