Phenylboronic acid (2.14 g, 17.59 mmol), potassium phosphate (4.50 g, 21.20 mmol), tetrakis(triphenylphosphine)palladium(0) (0.283 g, 0.24 mmol) and 3-iodo-5-nitro-benzoic acid methyl ester (3.00 g, 9.77 mmol) in dioxane (30 mL) were heated at 80° C. for 3 h. Saturated ammonium chloride was added and the product was extracted, washed with water, brine, dried over magnesium sulfate, and concentrated to dryness. Purification by chromatography gave 1.85 g of 5-nitro-biphenyl-3-carboxylic acid methyl ester, as a white solid.
