N-Propargylmorpholine (171 mg, 1.37 mmol) was added to a solution of methyl (E)-[4-[3-(4-iodophenyl)-3-(3-trifluoromethylphenyl)allyloxy]-2-methylphenoxy]acetate (400 mg, 0.68 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, 0.108 mmol) and tetrakis(triphenylphosphine)-palladium (62 mg, 0.054 mmol) were added. The reaction mixture was degassed once more and then stirred at ambient temperature for 2 days under argon. The mixture was evaporated in vacuo; the residue was dissolved in ethyl acetate (50 mL) and the solution was washed with water (2×15 mL) and brine (10 mL). The organic solution was dried with anhydrous magnesium sulfate and its evaporation gave oil that was purified by flash column chromatography (silica gel Fluka 60, hexanes/ethyl acetate 1:1) yielding methyl (E)-[2-methyl-4-[3-[4-[3-(morpholin-4-yl)propynyl]phenyl]-3-(3-trifluoromethylphenyl)allyl-oxy]phenoxy]acetate as oil.
