Reaktionsschritte

Sodium carbonate (11.13 g) was added portionwise to a stirred solution of dihydroxy-(3-methoxyphenyl)borane (5.85 g) and 3-iodobenzoic acid (8.68 g) in water (138 ml) at room temperature, and then palladium(II) acetate (78.6 mg) was added portionwise thereto at the same temperature. The resulting mixture was stirred at the same temperature for 4 hours. The reaction mixture was filtered, then the filtrate was washed twice with diethyl ether and adjusted to pH 2.0 with 6N hydrochloric acid. The precipitated powder was collected by filtration and dissolved in ethyl acetate. The solution was dried over magnesium sulfate and evaporated in vacuo. The residue was washed with n-hexane to afford 3'-methoxy-3-biphenylcarboxylic acid (4.34 g) as a powder.
