Reaction Steps

To a degassed solution of the ester (486 mg, 0.877 mmol; prepared as described in example 38), 1-(N,N-dimethylamino)prop-2-yne (150 mg, 1.80 mmol) and diisopropyl amine (0.589 mL, 4.24 mmol) in anhydrous tetrahydrofuran (12 mL), bis(triphenylphosphine)-palladium(II) dichloride (47 mg, 0.067 mmol) and copper(I) iodide (14.0 mg, 0.074 mmol) were added. The reaction mixture was stirred at ambient temperature for 6 h under nitrogen. The solvents were evaporated in vacuo and the residue was purified by flash column chromatography (silica gel Fluka 60, chloroform/methanol 100:0-95:5) yielding methyl (Z)-[4-[3-(4-cyclopropylphenyl)-3-[4-[3-(N,N-dimethylamino)propynyl]phenyl]allyloxy]-2-methyl-phenoxy]acetate as yellow oil.
