Abstract

By reaction of 2-chlorobenzimidazole with methyl-, ethyl-, and 2-hydroxyethylhydrazine we have synthesized the corresponding 2-(1′-alkylhydrazino)benzimidazoles for the first time. By refluxing the latter in alcohols with acetyl(benzoyl)acetone they form 1-(2-benzimidazolyl)-1-alkylhydrazones and, without solvent, form 1,35-trisubstituted 1,2,4-triazepino[4,3-a]benzimidazoles.
