Procedure

A mixture of 1-ethynyl-4-trifluoromethyl-benzene (159 mg, 0.94 mmol), (4-{3-[3-bromo-5-(3-morpholin-4-yl-prop-1-ynyl)-phenyl]-prop-2-ynyloxy}-2-methyl-phenoxy)-acetic acid methyl ester (160 mg, 0.31 mmol, example 6), Pd(PPh3)2Cl2 (36 mg, 0.031 mmol), CuI (16 mg, 0.087 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 ethyl acetate/methanol mixtures to give (2-methyl-4-{3-[3-(3-morpholin-4-yl-prop-1-ynyl)-5-(4-trifluoromethyl-phenylethynyl)-phenyl]-prop-2-ynyloxy}-phenoxy)-acetic acid methyl ester in 18 mg (10%) yield.
