2,2'-[1,4 (1,3)-Phenylenedi(methylene)]bis-1H-benzimidazole derivatives were obtained from the reaction of 1,4- or (1,3)-bisiminoester hydrochloride and o-phenylenediamine derivatives under microwave irradiation. Ester and hydrazide derivatives were prepared from a free NH group. This practical method revealed good results for yield, reaction time, and quick isolation of products.
从1,4-或(1,3)-双亚氨基酯盐酸盐与邻苯二胺衍生物的反应中获得2,2'-[1,4(1,3)-苯撑二(亚甲基)]双-1H-苯并咪唑衍生物在微波照射下。由游离NH基制备酯和酰肼衍生物。这种实用的方法显示出良好的收率,反应时间和产物快速分离结果。
