Condensation of 2-ethoxymethylene-1,3-dicarbonyl compounds with 5-aminopyrazole (I) was examined and several kinds of 6,7-disubstituted pyrazolo [1,5-a] pyrimidines were obtained. In the reaction of ethyl 2-cyano-3-ethoxyacrylate with (I), ethyl 2-cyano-3-(5-pyrazolylamino) acrylate (II) as the intermediate was isolated.
