Regioselective Synthesis and Characterization of New 3-Aryl-7-trifluoromethyl-[1,2,4]triazolo[4,3-a]pyrimidines

[摘要]：The regioselective synthesis and characterization of a new series of 3-aryl-7-trifluoromethyl[1,2,4]triazolo[4,3-a] pyrimidines from the oxidative heterocyclization of 2-(N'-benzylidenehydrazino)-4-trifluoromethylpyrimidines with copper dichloride is described.
