Reaction Steps

To N,N-dimethylacetamide 2.5 mL solution of tert-butyl 4-bromo-2-(4-fluoroanilino)benzoate 80 mg were added 3-(hydroxymethyl)phenylboronic acid 50 mg, sodium carbonate 58 mg and polymer-carried di(acetato)dicyclohexylphenylphosphine palladium(II) 7.0 mg, and it was stirred at 110° C. for 19 hours. After the reaction mixture was cooled to room temperature, polymer-carried di(acetato)dicyclohexylphenylphosphine palladium (II) 7.0 mg were added to it, and it was stirred at 110° C. for 30 hours. After the reaction mixture was cooled to room temperature, insoluble matter was filtrated, and ethyl acetate and 10% citric acid aqueous solution were added to it. The organic layer was separated and collected,dried over anhydrous magnesium sulfate after sequential washing with 10% citric acid aqueous solution and saturated sodium chloride aqueous solution, and the solvent was removed under reduced pressure. The obtained residue was refined by silica gel column chromatography [Trikonex company, Flash Tube 2008, eluent; hexane:ethyl acetate=4:1] to give tert-butyl 2-(4-fluoroanilino)-4-(3-(hydroxymethyl)phenyl)benzoate.
