Procedure

N-Propargylmorpholine (0.64 g, 5.1 mmol) was added under nitrogen atmosphere to a degassed solution of ethyl (Z)-[7-[3-(4-iodophenyl)-3-(4-trifluoromethylphenyl)allyloxy]-benzo[b]furan-4-yl]oxyacetate (0.68 g, 1.09 mmol) in a mixture of tetrahydrofuran (20 mL) and triethylamine (10 mL) The solution was cooled to 0° C., tetrakis(triphenylphosphine)palladium (0.17 g, 0.147 mmol) and copper(I) iodide (0.03 g, 0.16 mmol) were added. The reaction mixture was stirred at ambient temperature for 120 h, diluted with 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 ethyl (E)-[7-[3-[4-[3-(morpholin-4-yl)propynyl]phenyl]-3-(4-trifluoromethylphenyl)allyloxy]benzo[b]furan-4-yl]oxyacetate.
