Versuchsvorschrift

After a 2M aqueous sodium carbonate solution (1.5 ml), tris(dibenzylideneacetone)dipalladium (0) (23 mg, 25 μmol) and bis(2-diphenylphosphinophenyl)ether (DPEphos) (28 mg, 52 μmol) were added to a solution of methyl (3-chloro-4-{[(trifluoromethyl)sulfonyl]oxy}phenyl)acetate (317 mg, 1.0 mmol) obtained in Example (23-1) and 4-methoxyphenylboronic acid (152 mg, 1.0 mmol) in a mixture of toluene-ethanol (5:1, 9 ml), the mixture was stirred at 100° C. for 5 hours under stirring. After the temperature of the reaction mixture was returned to room temperature, the mixture was poured into water and extracted with ethyl acetate (three times). The organic layer was successively washed with water (twice) and a saturated aqueous NaCl solution and dried with anhydrous sodium sulfate. The solvent was removed under reduced pressure to give methyl (2-chloro-4′-methoxy-1,1′-biphenyl-4-yl)acetate as a solid (192 mg, yield: 66%).
