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-aryl[1,2,4]triazolo[1,5-a]pyrimidines (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
2-(芳酰氨基)嘧啶(4)已经通过用PCl5处理然后在丙酮水溶液中叠氮分解转化为1-(2-嘧啶基)-5-芳基-1H-四唑(6)。6 在萘烷中的热解得到 2-芳基 [1,2,4] 三唑并 [1,5-a] 嘧啶 (8)。提出了从 6 形成 8 的合理途径。所有化合物的结构均已通过元素分析和光谱数据确定。
