3-{4-[1-(4-bromo-phenylsulfanyl)-3-methyl-butyl]-benzoylamino}-propionic acid methyl ester (350 mg, 0.75 mmol), potassium carbonate (311 mg, 2.25 mmol), 4-triflouromethoxylphenyl boronic acid (311 mg, 1.5 mmol) and tetrakis-(triphenylphosphine)palladium (87 mg, 0.075 mmol) are place in a flask. After the reaction is purged with N2 for several times, THF/H2O (20 ml/5 ml) is added. The resulting solution is refluxed overnight, loaded on silica gel, eluted with hexane and ethyl acetate to give 3-{4-[3-Methyl-1-(4′-trifluoromethoxy-biphenyl-4-ylsulfanyl)-butyl]-benzoylamino}-propionic acid methyl ester (294 mg) as a yellow solid.
