실험 절차

Methyl (Z)-[4-[3-(4-Fluorophenyl)-3-(4-iodophenyl)allyloxy]-2-methylphenoxy]acetate (400 mg, 0.75 mmol; example 10) was dissolved in anhydrous tetrahydrofuran (10 mL); anhydrous triethylamine (20 mL) and a solution of 3-(methylsulfanyl)propyne (130 mg, 1.51 mmol) in anhydrous tetrahydrofuran (2 mL) were added. Resulting solution was degassed and copper(I) iodide (23 mg, 0.12 mmol) and tetrakis(triphenylphosphine)palladium (70 mg, 0.06 mmol) were added under nitrogen atmosphere. Reaction mixture was stirred at ambient temperature overnight, the resulting suspension was filtered through a paddle of silica gel and silica gel was thoroughly washed with ethyl acetate. The filtrate was evaporated in vacuo; the obtained residue was dissolved in dichloromethane and the solution was washed with water (2×30 mL) and brine (2×30 mL), dried over anhydrous magnesium sulfate and evaporated in vacuo. The residue was purified by column chromatography (silica gel Fluka 60, hexanes/ethyl acetate 90:10) yielding methyl (E)-[4-[3-(4-fluorophenyl)-3-[4-[3-(methylsulfanyl)propynyl]phenyl]allyloxy]-2-methylphenoxy]acetate as yellow oil.
