Pyrimidine aryl ether derivatives have attracted widespread attention from chemists for their diverse biological activity and pharmacological properties. In this paper, a series of pyrimidine-2-arylether derivatives were synthesized with moderate to good yield by using 2-(trimethylsilyl)phenyl trifluoromethanesulfonate as a source of benzyne to react with 2-hydroxypyrimidine. Compared with the traditional method, this method has the advantages of transition-metal-free, easy preparation of 2-aryloxypyrimidine derivatives, wide functional group compatibility and high yield.

Key words: benzyne, pyrimidine derivatives, nucleophilic addition, 2-phenoxy pyrimidine
