Microwave Supported Solvent Free Reaction of EMME in the Synthesis of Pyrazolopyrimidopyrimidines

Diethyl ethoxy-methylenemalonate the versatile reagent used to synthesize pyrazolopyrimidopyrimidines (3) as antimicrobial agents from the reaction between EMME and 1-substituted 3-(methylthio) 3H-pyrazolo [3,4-d]pyrimidine-4-amines (1) using Gould Jacob reaction. A comparison of conventional and microwave supported solvent-free reaction has been studied.
