실험 절차

A degassed (argon) solution of 96.0 mg (0.33 mmol) (2-methyl-4-prop-2-ynylsulfanyl-phenoxy)-acetic acid tert-butyl ester, 0.053 ml (0.36 mmol) 1-iodo-4-trifluoromethyl-benzene and 0.086 (0.621 mmol) Et3N in 1 ml DMF was treated with 37.9 mg (0.03 mmol) Pd(PPh3)4 and 12.5 mg (0.07 mmol) of CuI. After stirring for 2 h at room temperature, the reaction was distributed between 1N HCl and ether (three times). Washing of the organic layer with saturated aqueous NH4Cl solution and brine, drying (Na2SO4) and evaporation of the solvents, followed by flash chromatography (SiO2, n-heptane/EtOAc 1 to 5%), yielded 76 mg of the title compound as yellow oil.
