Versuchsvorschrift

N-Propargylpyrrolidine (300 mg, 2.75 mmol) was added under nitrogen atmosphere to a degassed solution of methyl (Z)-[4-[3-(4-chlorophenyl)-3-(4-iodophenyl)allyloxy]-2-methylphenoxy]acetate (500 mg, 0.91 mmol) in a mixture of tetrahydrofuran (8 mL) and triethylamine (8 mL) The solution was cooled, tetrakis(triphenylphosphine)palladium (96 mg, 0.083 mmol) and copper(I) iodide (27.6 mg, 0.145 mmol) were added. The reaction mixture was stirred at ambient temperature for 72 h, diluted with benzene (100 mL) and the resulting mixture was washed with water (2×50 mL). The organic solution was dried with anhydrous potassium carbonate and subsequently evaporated in vacuo. The residue was purified by column chromatography (silica gel Fluka 60, benzene-chloroform/ether 2:1) yielding methyl (E)-[4-[3-(4-chlorophenyl)-3-[4-[3-(pyrrolidin-1-yl)propynyl]phenyl]allyloxy]-2-methyl-phenoxy]-acetate.
