Reaction Conditions

Reaction Steps

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). Filtration and concentration of solvent gave a yellow residue which was purified by Prep. HPLC to afford a yellowish oil as 2-chloro-4-phenyl-pyrimidine.
