Abstract

Some derivatives of benzimidazole were synthesized by nucleophilic substitution of 2- substituted-1H-benzimidazole. The resulting ethyl (2-substituted-1H-benzimidazol-1-yl) acetate on treatment with hydrazine hydrate yielded 2-(2-substituted-1H-benzimidazol-1-yl) acetohydrazide, which on further reaction with one equivalent of different aliphatic or aromatic carboxylic acids in the presence of phosphoryl chloride afforded the ...
