Procedure

N-Propargylmorpholine (270 mg, 2.16 mmol) was added under nitrogen atmosphere to a degassed solution of methyl (Z)-[4-[3-(4-iodophenyl)-3-(2-methylbenzo[b]furan-5-yl)allyloxy]-2-methylphenoxy]acetate (400 mg, 0.68 mmol; prepared as described in example 25) in a mixture of tetrahydrofuran (6 mL) and triethylamine (6 mL) The solution was cooled to 0° C., tetrakis(triphenylphosphine)palladium (71 mg, 0.061 mmol) and copper(I) iodide (21 mg, 0.11 mmol) were added. The reaction mixture was stirred at ambient temperature for 96 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 methyl (E)-[2-methyl-4-[3-(2-methyl benzo[b]furan-5-yl)-3-[4-[3-(morpholin-4-yl)propynyl]phenyl]-allyloxy]phenoxy]acetate.
