Reaction Steps
A mixture of 5-bromo-2-chloropyrimidine (500 mg, 2 mmol), 4-fluorophenylboronic acid (430 mg, 3.1 mmol), [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium(II) dichloromethane complex (1:1) (210 mg, 0.26 mmol) and potassium carbonate (1.8 g, 13 mmol) in 1,4-dioxane (6 mL) was irradiated under microwave at 120° C. for 30 min. After cooling, the solvent was evaporated. The residue was purified by flash chromatography eluting with ethyl acetate in hexanes to give the desired product. (376 mg) LCMS: (M+H)=209.0.
