(Chemical Equation Presented) The Suzuki-Miyaura reaction of some 4,6-dichloropyrimidines bearing methylthio-, methyl-, amino-, cyano-, formyl-, and nitro groups in positions 2 and/or 5 of the pyrimidine ring with arylboronic acids has been investigated. Influence of palladium catalyst, ligand, base, and solvent on the reaction outcome was studied. The reaction was found to give the corresponding 4,6-diarylpyrimidines in reasonable yields using Pd(OAc) 2/PPh3/K3PO4 or Pd(PPh 3)2Cl2/K3PO4 as catalyst systems.
