A two-step procedure for the synthesis of 4-arylpyrimidines from inexpensive 4,6-dichloropyrimidine via a Suzuki-Miyaura/hydrodechlorination reaction sequence is described. The reaction resulted in the predominant formation of mono-arylated product. The cross-coupling of 4-chloro-6-substituted pyrimidines with various aryl/heteroarylboronic acids also furnished 4,6-disubstituted pyrimidines in acceptable yields.

The Pd-catalyzed regioselective C-H activation/arylation, /iodination, and/acetoxylation reactions of 4-arylpyrimidines using aryl iodides, N-iodosuccinimide, and (diacetoxyiodo)benzene respectively as coupling partners are described. Suzuki-Miyaura coupling and Sonogashira reactions of the resulting aryl iodides are demonstrated. The scalability of the C-H activation/functionalization starting with readily accessible 4-aryl pyrimidines is also reported.
