Reaction Conditions

Reaction Steps

To N,N-dimethylacetamide 2.5 mL solution of methyl 4-bromo-2-(4-fluoroanilino)benzoate 70 mg were added 3-methoxyphenylboronic acid 49 mg, sodium carbonate 57 mg and polymer-carried bis(acetato)triphenylphosphine palladium (II) 31 mg at room temperature, and it was stirred at 90° C. for 12 hours. After the reaction mixture was cooled to room temperature, insoluble matter was filtrated, ethyl acetate and 1.0 mol/L hydrochloric acid were added to it. The organic layer was separated and collected, dried over anhydrous magnesium sulfate after sequential washing with 1.0 mol/L hydrochloric acid and saturated sodium chloride aqueous solution, and the solvent was removed under reduced pressure. To the obtained residue were added 2.0 mol/L sodium hydroxide aqueous solution 1.0 mL and ethanol 6.0 mL, and it was stirred at room temperature for 1 hour. 0.5 mol/L Hydrochloric acid was added to the reaction mixture, solid matter was filtrated to give 2-(4-fluoroanilino)-4-(3-methoxyphenyl)benzoic acid 10 mg of pale yellow solid.
