To a degassed solution of the above ester (1 g, 1.705 mmol), N-propargylmorpholine (440 mg, 3.515 mmol) and diisopropylamine (1.12 mL, 7.96 mmol) in anhydrous tetrahydrofuran (27 mL), bis(triphenylphosphine)palladium(II) dichloride (95 mg, 0.135 mmol) and copper(I) iodide (27.0 mg, 0.142 mmol) were added. The reaction mixture was stirred at 50° C. overnight under nitrogen. The solvents were evaporated in vacuo and the residue was twice purified by flash column chromatography (silica gel Fluka 60, chloroform/methanol 100:0-95:5 and then chloroform/ethyl acetate/methanol 80:13:7) yielding methyl (E)-[4-[3-(4-cyclopropylsulfanylphenyl)-3-[4-[3-(morpholin-4-yl)propynyl]phenyl]allyloxy]-2-methylphenoxy]acetate as yellow oil.
