Versuchsvorschrift

Dimethyl(prop-2-ynyl)amine (114 mg, 1.374 mmol) was added to a solution of methyl (E)-[4-[3-(4-iodophenyl)-3-(3-trifluoromethylphenyl)allyloxy]-2-methylphenoxy]acetate (400 mg, 0.687 mmol; prepared as described in example 34) in a mixture of tetrahydrofuran (12 mL) and triethylamine (12 mL). The mixture was degassed and copper(I) iodide (20 mg, 0.109 mmol) and tetrakis(triphenylphosphine)palladium (63 mg, 0.054 mmol) were added. The reaction mixture was stirred at ambient temperature for 24 h. Further portions of dimethyl(prop-2-ynyl)amine (57 mg, 0.687 mmol), copper(I) iodide (10 mg, 0.0545 mmol) and tetrakis(triphenylphosphine)palladium (31.5 mg, 0.027 mmol) were added and the reaction mixture was stirred under argon for additional 20 h. The mixture was evaporated in vacuo; the residue was dissolved in ethyl acetate (30 mL) and was washed with water (2×15 mL) and brine (10 mL). The organic solution was dried with anhydrous magnesium sulfate and evaporated in vacuo. The residue was purified by flash column chromatography (silica gel Fluka 60, hexanes/ethyl acetate 3:5) yielding methyl (E)-[4-[3-[4-[3-(N,N-dimethylamino)propynyl]phenyl]-3-(3-trifluoromethylphenyl)allyloxy]-2-methylphenoxy]acetate as oil.
