Microwave-assisted synthesis of substituted pyrazoles and pyrazolo [3,4-d]thiopyrimidines

Ethyl(ethoxymethylene)cyanoacetate and ethoxymethylene malononitrile were synthesized from the reaction of malononitrile or ethylcyanoacetate with triethyl orthoformate or orthoacetate in N, N-dimethylacetamide under microwave irradiation. In a similar manner, substituted pyrazoles were synthesized from the reaction of ethyl (ethoxymethylene)cyanoacetate and ethoxymethylene malononitrile with phenylhydrazine. These pyrazoles were converted to pyrazolo[3,4-d]thiopyrimidines upon treatment with arylisothiocyanate and thiourea under microwave irradiation. Copyright Taylor & Francis Group, LLC.
