[4-(3-Bromo-5-hydroxy-benzylsulfanyl)-2-methyl-phenoxy]-acetic acid ethyl ester (2 g; 4.9 mmol), 3-phenyl-1-propyn (1.7 g; 14.6 mmol), bis(triphenylphosphine)palladium (II) chloride (0.27 g; 0.39 mmol) and copper iodide (0.056 g; 0.29 mmol) were dissolved in a mixture of triethylamine (5 mL) and DMF (10 mL) under an atmosphere of nitrogen. The reaction mixture was reacted in a microwave oven at 100° C. for 1 h. Further 3-phenyl-1-propyn (1.7 g; 14.6 mmol) was added and the reaction mixture was reacted in a microwave oven at 100° C. for further 1 h. The reaction mixture was purified by preparative HPLC (method A). Yield: 0.8 g. HPLC-MS: m/z: 434.6 (M+1); Rt: 2.43 min.
