Design and Synthesis of Novel Anthranilic Diamides Containing 5,7-Dimethyl[1,2,4]Triazolo[1,5- a ]Pyrimidine

A new kind of anthranilic diamides containing 5,7-dimethyl[1,2,4]triazolo[1,5- a]pyrimidine were designed and synthesised. Their structures were identified by means of elemental analysis, IR, 1 H NMR and MS spectra. As the key intermediate, ethyl 5,7-dimethyl[1,2,4]triazolo[1,5- a]pyrimidine-2-carboxylate (7) was synthesised by applying microwave irradiation.
