実験手順

[4-(3-Bromo-5-hydroxy-phenylsulfanyl)-2-methyl-phenoxy]-acetic acid ethyl acetate (2.3 g; 5.79 mmol), phenylacetylene (1.9 mL; 17.4 mmol), bis(triphenylphosphine)palladium (II) chloride (0.33 g; 0.46 mmol) and copper iodide (0.07 g; 0.35 mmol) were dissolved in a mixture of triethylamine (7 mL) and DMF (8 mL) under an atmosphere of nitrogen. The reaction mixture was reacted in a microwave oven at 100° C. for 1 h. The reaction mixture was evaporated to dryness, and 5% aqueous citric acid and ethyl acetate was added. The organic phase was separated, dried and evaporated to dryness. The crude product was purified by flash chromatography (ethyl acetate:heptane 1:10→1:3). Yield: 1.2 g. HPLC-MS: m/z: 419 (M+); Rt: 2.52 min.
