To a solution of 2,4-dichloro-pyrimidine (1 eq) in THF/H2O (4:3) solution, was added 4-chloro phenyl boronic acid (1 eq), Pd(PPh3)4 (0.01 eq) and Na2CO3 (2 eq) under Ar. The reaction mixture was stirred at reflex for overnight. EtOAc (10 mL) was added. The organic phase was separated, dried over Na2SO4, and concentrated. The residue was purified by column chromatography (Ethyl acetate:Hexane: 1:3) to give the desired product as a white powder (71% yield. MS: (ESI), M/Z, 225 (M+1). Retention time: 1.07 min (FA-non polar).
