Microwave irradiation for accelerating synthesis of [1,2,4]Triazole[4,3-a ]-pyrimidines based on isoflavones

Zhang, Zun-Ting,Xie, Juan,Zhu, Mu-Lin,Xue, Dong

supporting information; experimental part, p. 1825 - 1828 (2010/10/21)

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. Georg Thieme Verlag Stuttgart.
