Simple microwave-assisted ligand-free Suzuki cross-coupling: Functionalization of halo-pyrimidine moieties

An advantageous ligand-free protocol for Suzuki couplings is described. The synthetic procedure entails microwave irradiation for the reduction of the reaction times and the use of silica cartridges for the purification. Dihalo-pyrimidine structures, interesting scaffolds in medicinal chemistry, were chosen as test compounds.
