2-Aroylamino)pyrimidines (4) have been converted into 1-(2-pyrimidyl)-5-aryl-1H-tetrazoles (6) by treatment with PCl5 followed by azidolysis in aqueous acetone solution.Pyrolysis of 6 in decalin gave 2-aryltriazolopyrimidines (8).A reasonable pathway for the formation of 8 from 6 is suggested.Structures of all the compounds have been established by elemental analysis and spectral data.
