Procedure

A solution of the above ester (480 mg, 0.908 mmol) in a mixture of tetrahydrofuran (5 mL) and triethylamine (5 mL) was degassed and N-propargylmorpholine (237 mg, 1.89 mmol) was added under argon atmosphere. The solution was cooled, tetrakis(triphenylphosphine)palladium (84 mg, 0.073 mmol) and copper(I) iodide (27.6 mg, 0.145 mmol) were added. The reaction mixture was stirred at ambient temperature for 6 h and then left to stand overnight. The mixture was evaporated in vacuo; the residue was dissolved in dichloromethane (20 mL) and the formed solution was washed with water (2×10 mL). The organic solution was dried with anhydrous magnesium sulfate and subsequently evaporated in vacuo. The residue was purified by flash column chromatography (silica gel Fluka 60, hexanes/ethyl acetate 1:1) yielding methyl (Z)-[2-methyl-4-[3-(4-methylphenyl)-3-[4-[3-(morpholin-4-yl)propynyl]phenyl]allyloxy]phenoxy]acetate.
