Procedure

To a degassed solution of methyl (Z)-[4-[3-(4-cyclopropylsulfanylphenyl)-3-(4-iodophenyl)allyloxy]-2-methylphenoxy]acetate (480 mg, 0.818 mmol; prepared as described in example 53), N,N-dimethylpropargylamine (0.175 mL, 1.64 mmol) and diisopropylamine (0.539 mL, 3.85 mmol) in anhydrous tetrahydrofuran (10 mL), bis(triphenylphosphine)palladium(II) dichloride (29 mg, 0.041 mmol) and copper(I) iodide (13 mg, 0.068 mmol) were added. The reaction mixture was stirred at ambient temperature over night under nitrogen. The solvents were evaporated in vacuo and the residue was purified by flash column chromatography (silica gel Fluka 60, dichloromethane/methanol 99:1-98:2) yielding methyl (E)-[4-[3-(4-cyclopropylsulfanylphenyl)-3-[4-[3-(N,N-dimethylamino)propynyl]phenyl]allyloxy]-2-methylphenoxy]acetate as yellow oil.
