5.36 g (purity 91%, 26.03 mmol) of 5-chloro-2-methoxypyridin-4-ylboronic acid and 5.12 g (23.66 mmol) of 2-bromo-4-chlorobenzonitrile in the presence of [1,1-bis(diphenylphosphino)ferrocene]palladium(II) chloride/dichloromethane monoadduct were reacted according to General Method 2A. After work-up, the crude product was then purified by flash chromatography (silica gel 60, cyclohexane/dichloromethane mixtures). Yield: 4.11 g (purity 91%, 52% of theory)
