実験手順

N,N-Dimethylpropargylamine (0.11 mL, 1.03 mmol) and diisopropylamine (0.34 mL, 2.42 mmol) were added to a solution of methyl (Z)-[4-[3-(4-iodophenyl)-3-(4-trifluoromethylphenyl)allyloxy]-2-methylphenoxy]acetate (300 mg, 0.515 mmol; example 4) in tetrahydrofuran (10 mL). The mixture was degassed and copper(I) iodide (8 mg, 0.042 mmol) and bis(triphenylphosphine)palladium(II) dichloride (18 mg, 0.026 mmol) were added. The reaction mixture was stirred at ambient temperature for 20 h and evaporated in vacuo. The residue was purified by flash column chromatography (silica gel Fluka 60, dichloromethane-/methanol 98:2) yielding methyl (E)-[2-methyl-4-[3-[4-[3-(N,N-dimethylamino)propynyl]-phenyl]-3-(4-trifluoromethylphenyl)allyloxy]phenoxy]acetate as brown oil.
