Microwave Irradiation for Accelerating Synthesis of [1,2,4]Triazole[4,3-a]-pyrimidines Based on Isoflavones

Microwave irradiation was used to accelerate the cyclocondensation of isoflavones and 3-amino-1,2,4-triazoles in the presence of sodium methoxide to produce 6,7-diphenyl[1,2,4]-triazolo[4,3-a]pyrimidines in good to moderate yields.
