Procedure

N-(2-Hydroxyethyl)-N-propargylmethylamine (300 mg, 2.65 mmol) was added under nitrogen atmosphere to a degassed solution of methyl (Z)-[4-[3-(4-chlorophenyl)-3-(4-iodophenyl)allyloxy]-2-methylphenoxy]acetate (450 mg, 0.82 mmol; prepared as described in example 7) in a mixture of tetrahydrofuran (10 mL) and triethylamine (8 mL) The solution was cooled to 0° C., tetrakis(triphenylphosphine)palladium (85 mg, 0.073 mmol) and copper(I) iodide (22 mg, 0.115 mmol) were added. The reaction mixture was stirred at ambient temperature for 48 h, dissolved in benzene (100 mL), decanted and evaporated in vacuo. The residue was purified by column chromatography (silica gel Fluka 60, benzene/ethyl acetate 1:0-0:1) yielding methyl (E)-[4-[3-(4-chlorophenyl)-3-[4-(3-[N-(2-hydroxyethyl)-N-methylamino]-propynyl]-phenyl]allyloxy]-2-methylphenoxy]acetate.
