반응 단계

A mixture of 3-fluoro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzonitrile (14.0 g), 4-bromo-2-methylpyridine (5.84 mL), tetrakis(triphenylphosphine)palladium(0) (5.24 g) and 2N aqueous sodium carbonate solution (91 mL) in 1,2-dimethoxyethane (20 mL) was stirred at 80° C. for 30 min under a nitrogen atmosphere. The reaction mixture was allowed to cool to room temperature, and diluted with water, and the mixture was extracted with ethyl acetate. The organic layer was separated, and dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (6.41 g).
