- Abstract
Cyanoethyl-, ethyl-, and methylhydrazones of 2-phenacyl-1H-benzimidazole undergo recyclization on condensation with aroyl chlorides or dimethylformamide with the formation of 5-(o-aroyl-aminoanilino)pyrazoles or 1-(5-pyrazolyl)-1H-benzimidazoles. The reaction with aroyl chlorides occurs selectively only with the corresponding cyanoethylhydrazone.
