Procedure

N-Propargylpyrrolidine (113 mg, 1.04 mmol) and diisopropylamine (0.339 mL, 2.42 mmol) were added to a solution of methyl (Z)-[4-[3-(4-iodophenyl)-3-(4-trifluoromethyl-phenyl)-allyloxy]-2-methylphenoxy]acetate (300 mg, 0.515 mmol; prepared as described in 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 21 h. Further portions of N-propargylpyrrolidine (113 mg, 1.04 mmol), diisopropylamine (0.339 mL, 2.42 mmol), copper(I) iodide (8 mg, 0.042 mmol) and bis(triphenylphosphine)palladium(II) dichloride (18 mg, 0.026 mmol) were added and reaction mixture was stirred at 50° C. for further 5 h and then evaporated in vacuo. The residue was purified by flash column chromatography (silica gel Fluka 60, dichloromethane/methanol 99:1-98:2) yielding methyl (E)-[2-methyl-4-[3-[4-[3-(pyrrolidin-1-yl)propynyl]phenyl]-3-(4-trifluoromethylphenyl)allyloxy]phenoxy]acetate as brown oil.
