SYNTHESIS AND REACTIONS OF 2-(1'-ALKYLHYDRAZINO)-BENZIMIDAZOLE WITH ACETYL(BENZOYL)ACETONE

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-alkyl hydrazones and, without solvent, form 1,3,5-trisubstituted 1,2,4-triazepinobenzimidazoles.
