N-Cyclopropyl-N-(prop-2-ynyl)amine (105 mg, 1.103 mmol) was added to a solution of methyl (Z)-[4-[3-(4-chlorophenyl)-3-(4-iodophenyl)allyloxy]-2-methylphenoxy]acetate (336 mg, 0.613 mmol; prepared as described in example 7) in a mixture of tetrahydrofuran (5 mL) and triethylamine (5 mL). The mixture was degassed and copper(I) iodide (19 mg, 0.1 mmol) and tetrakis(triphenylphosphine)palladium (58 mg, 0.05 mmol) were added. The reaction mixture was stirred at ambient temperature for 2 days, diluted with dichloromethane (40 mL), washed with water (2×15 mL), dried with anhydrous magnesium sulfate and evaporated in vacuo. The residue was purified by flash column chromatography (silica gel Fluka 60, hexanes/ethyl acetate 7:3) yielding methyl (E)-[4-[3-(4-chlorophenyl)-3-[4-[3-(N-cyclopropylamino)propynyl]phenyl]allyloxy]-2-methylphenoxy]acetate as oil.
