[4-(3-Bromo-5-hydroxy-phenylsulfanyl)-2-methyl-phenoxy]-acetic acid ethyl acetate (3 g; 7.55 mmol), 3-phenyl-1-propyn (2.63 g; 22.65 mmol), bis(triphenylphosphine)palladium (II) chloride (0.42 g; 0.60 mmol) and copper iodide (0.086 g; 0.45 mmol) were dissolved in a mixture of triethylamine (3 mL) and DMF (6 mL) under an atmosphere of nitrogen. The reaction mixture was reacted in a microwave oven at 100° C. for 11 h. The reaction mixture was evaporated to dryness, and portioned between 5% aqueous citric acid and ethyl acetate. The organic phase was dried and evaporated to dryness. The crude product was purified by preparative HPLC method A. Yield: 1.4 g. HPLC-MS: m/z: 433.3 (M+); Rt: min.
