摘要：

1H-3-methyl-4-ethoxycarbonyl-5-arylidenhydrazino-pyrazoles, obtained by the direct reaction between 1H-3-methyl-4-ethoxycarbonyl-hydrazino-pyrazole hydrochloride and substituted benzaldehydes in anhydrous alcoholic solution, are useful intermediates in preparing 1H-3-aryl-6-methyl-pyrazolo[5, 1-c][1,2,4]-triazoles. The obtained compounds, from which 12 are new compounds, were characterized by mass, IR, 1-H-NMR and 13-C-NMR spectrometry.
