To a solution of 2,4-dichloropyrimidine (149 mg, 1 mmol) in THF (5 mL), tetrakis(triphenylphosphine)palladium (23 mg, 2 mol %) and 0.5M solution of phenylzinc bromide (2.1 mL, 1.05 mmol) in THF were added. The reaction mixture was stirred at 50° C. for overnight. Then it was added saturated ammonium chloride solution and extracted with EtOAc twice. The organic layers were combined, washed with water and dried (MgSO4). Evaporation of solvent gave a yellow residue which was purified by Prep. HPLC to afford a yellowish oil as 2-chloro-4-phenyl-pyrimidine to carry on.
