실험 절차

1-Ethynyl-4-(hydroxymethyl)benzene (169 mg, 1.28 mmol) and diisopropylamine (0.40 mL, 2.85 mmol) were added to a solution of methyl (Z)-[4-[3-(4-tert-butylphenyl)-3-(4-iodophenyl)allyloxy]-2-methylphenoxy]acetate (364 mg, 0.638 mmol; prepared as described in example 30) in tetrahydrofuran (10 mL). The mixture was degassed and copper(I) iodide (10 mg, 0.053 mmol) and bis(triphenylphosphine)palladium(II) dichloride (22 mg, 0.031 mmol) were added. The reaction mixture was stirred at ambient temperature overnight, filtered and the filtrate was evaporated in vacuo. The residue was purified by flash column chromatography (silica gel Fluka 60, dichloromethane/methanol 99:1) yielding methyl (Z)-[4-[3-(4-tert-butylphenyl)-3-[4-[4-(hydroxymethyl)phenylethynyl]phenyl]allyloxy]-2-methylphenoxy]acetate as brown oil.
