실험 절차

A solution of methyl (Z)-[4-[3-(4-iodophenyl)-3-(4-trifluoromethylphenyl)allyloxy]-2-methylphenoxy]acetate (370 mg, 0.636 mmol; example 4) in a mixture of tetrahydrofuran (5 mL) and triethylamine (5 mL) was degassed and 2-ethynylpyridine (118 mg, 1.144 mmol) was added under argon atmosphere. The solution was cooled; tetrakis(triphenylphosphine)palladium (59.0 mg, 0.051 mmol) and copper(I) iodide (19.3 mg, 0.102 mmol) were added. The reaction mixture was stirred at ambient temperature for 48 h. The mixture was evaporated in vacuo and the residue was dissolved in dichloromethane (60 mL). The solution was washed with water (2×20 mL), dried with anhydrous magnesium sulfate and evaporated in vacuo. The residue was purified by flash column chromatography (silica gel Fluka 60, hexanes/ethyl acetate 7:3) yielding methyl (E)-[2-methyl-4-[3-[4-(pyridin-2-ylethynyl)phenyl]-3-(4-trifluoromethyl phenyl)allyloxy]phenoxy]acetate.
