After the reaction mixture was cooled to room temperature, 6 mg of polymer supported di(acetato) dicyclohexylphenylphosphine palladium(II) was added and stirred at 110° C. for 24 hours. After the reaction mixture was cooled to room temperature, insoluble were removed by filtration and ethyl acetate and 10% citric acid aqueous solution were added. The organic layer was separated and dried over anhydrous magnesium sulfate after washed with 10% citric acid aqueous solution and a saturated sodium chloride aqueous solution sequentially, and the solvent was evaporated under reduced pressure. The obtained residue was purified with silica gel column chromatography [Flash Tube 2008 manufactured by Trikonex company, eluent; hexane: ethyl acetate=4:1] to obtain tert-butyl 2-(benzamido)-4-(4-phenoxyphenyl)benzoate.
