Tetrakis(triphenylphosphine)palladium(0) (0.40 g) was added to a mixture of methyl 3-fluoro-2-hydroxy-4-methyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzoate (2.13 g), 1-(4-(chloromethyl)phenyl)-1H-pyrazole (1.32 g), sodium carbonate (1.46 g), DME (30.0 mL) and water (10.0 mL) under argon atmosphere, and the mixture was stirred overnight at 80° C. The reaction mixture was allowed to be cooled to room temperature, water was added thereto, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, 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 (0.33 g).
