Reaction Steps

Dry triethylamine (8 mL), copper(I) iodide (29 mg, 0.152 mmol) and tetrakis(triphenylphosphine)palladium (68 mg, 0.059 mmol) were added to a degassed solution of the above ester (448 mg, 0.931 mmol) and N-propargylmorpholine (291 mg, 2.32 mmol) in dry tetrahydrofuran (18 mL). In atmosphere of argon, the resulting mixture was heated at 50° C. for 10 h, cooled down and subsequently evaporated in vacuo. The residue was dissolved in dichloromethane (20 mL); the solution was washed with water (3×10 mL), dried with anhydrous magnesium sulfate and evaporated in vacuo. The residue was purified by column chromatography (silica gel Fluka 60, hexanes/ethyl acetate 4:1-1:1) yielding methyl (E)-[2-methyl-4-[3-[4-[3-(morpholin-4-yl)propynyl]phenyl]-3-phenylallyloxy]phenoxy]acetate as an oil.
