Synthesis of Aryl-Substituted Pyrimidines by Site-Selective Suzuki-—Miyaura Cross-Coupling Reactions of 2,4,5,6-Tetrachloropyrimidine.

Suzuki—Miyaura reactions of the tetrachloropyrimidine (I) allow a convenient synthesis of mono-, di, tri-, and tetraarylpyrimidines, which are not readily available by other methods.
