A simple and efficient procedure for the synthesis of novel 4-aryl pyrazolo[3,4-c]pyrazol-3(2H)-ones via a one-pot, three-component reaction between 2-cyano-N-methylacetamide, aryl aldehydes, and hydrazine hydrate in the presence of Et3N in DMF is reported. Products are obtained in good yields and their structures are supported by their spectroscopic data and combustion analysis.[GRAPHICS].
