To toluene 1.6 mL solution of tert-butyl 4-bromo-2-(4-fluoroanilino)benzoate 70 mg were added ethanol 0.60 mL, water 0.30 mL, 4-(dimethylamino)phenylboronic acid 47 mg, sodium hydrogen carbonate 48 mg and tetrakis(triphenylphosphine)palladium(0) 11 mg at room temperature, and it was heated and refluxed for 6 hours. After the reaction mixture was cooled to room temperature, ethyl acetate and water were added to it. The organic layer was separated and collected,dried over anhydrous magnesium sulfate after washing with saturated sodium chloride aqueous solution, and the solvent was removed under reduced pressure. The obtained residue was refined by silica gel column chromatography [Fuji SILYSIA Chemical Ltd., PSQ100B(spherical type), eluent; hexane:ethyl acetate=10:1] to give tert-butyl 4-(4-(dimethylamino)phenyl)-2-(4-fluoroanilino)benzoate.
