Essay

The first ring transformation of benzimidazole compounds into the pyrazoles were performed by the example of hydrazones of 2-acylmethyl-1H-benzimidazoles. A new approach to ring transformation - fixation or initiation by acylating reagents were proposed. As a result, the preparative methods of synthesis of the previously unknown 5-(o-aminoanilino)pyrazoles and 1-(5-pyrazolyl)benzimidazoles derivatives promising for subsequent transformations and searching for new practically useful substances were elaborated.
