A mixture of 2-chloro-5-fluoro-4-(4-fluoro-2-methoxyphenyl)pyrimidine (750 mg; 2.92 mmol), 3-[(ethylsulfanyl)methyl]aniline (376 mg; 2.24 mmol), chloro(2-dicyclohexylphosphino-2′,4′,6′-tri-iso-propyl-1,1′-biphenyl)[2-(2-aminoethyl)phenyl]palladium(II) methyl-tert-butylether adduct (139 mg; 0.17 mmol; ABCR GmbH & CO. KG) and 2-(dicyclohexylphosphino)-2′,4′,6′-triisopropylbiphenyl (80 mg; 0.17 mmol; Aldrich Chemical Company Inc.) and potassium phosphate (2.39 g; 11.24 mmol) in toluene (15 ml) and NMP (3 mL) was stirred at 130° C. for 3 hours. After cooling, the batch was diluted with ethyl acetate and washed with aqueous sodium chloride solution. The organic phase was filtered using a Whatman filter and concentrated. The residue was purified by chromatography (hexane/ethyl acetate 2:1) to give the pure product (536 mg; 1.38 mmol).
