A mixture of phenylacetylene (169 mg, 1.66 mmol), (4-{3-[3-bromo-5-(3-morpholin-4-yl-prop-1-ynyl)-phenyl]-prop-2-ynyloxy}-2-methyl-phenoxy)-acetic acid methyl ester (100 mg, 0.195 mmol, example 6), Pd(PPh3)2Cl2 (22 mg, 0.02 mmol), CuI (10 mg, 0.055 mmol) in dry DMF (2 ml) and triethylamine (2 ml) was heated in a microwave own for 1 hour at 60° C. in a sealed tube. The reaction mixture was filtered through Decalite and the filtrate was evaporated. The residue was purified on column chromatography using methylene chloride/THF mixtures to give (2-methyl-4-{3-[3-(3-morpholin-4-yl-prop-1-ynyl)-5-phenylethynylphenyl]-prop-2-ynyloxy}-phenoxy)-acetic acid methyl ester in 70 mg (67%) yield.
