Procedure
To a degassed solution of the ester (486 mg, 0.877 mmol; prepared as described in example 38), 1-(N,N-dimethylamino)prop-2-yne (150 mg, 1.80 mmol) and diisopropyl amine (0.589 mL, 4.24 mmol) in anhydrous tetrahydrofuran (12 mL), bis(triphenylphosphine)palladium(II) dichloride (47 mg, 0.067 mmol) and copper(I) iodide (14.0 mg, 0.074 mmol) were added. The reaction mixture was stirred at ambient temperature for 6 h under nitrogen. The solvents were evaporated in vacuo and the residue was purified by flash column chromatography (silica gel Fluka 60, chloroform/methanol 100:0-95:5) yielding methyl (Z)-[4-[3-(4-cyclopropylphenyl)-3-[4-[3-(N,N-dimethylamino)propynyl]phenyl]allyloxy]-2-methylphenoxy]acetate as yellow oil.
