Versuchsvorschrift

To a room temperature solution of 5-(4-bromo-3-methyl-phenoxymethyl)-1-(2,6-dichloro-phenyl)-4-isopropyl-1H-[1,2,3]triazole (50 mg, 0.110 mmol) in DMF (1 mL) are added 4-ethynyl-benzoic acid methyl ester (18 mg, 0.110 mmol) and triethylamine (107 μL, 0.770 mmol). The reaction mixture is degassed for 20 minutes with nitrogen. To the reaction mixture are added dichloro(bistriphenylphosphine) palladium (II) (8 mg, 0.011 mmol, 10 mol %) and zinc (II) triflate (40 mg, 0.110 mmol). The reaction mixture is heated to 80° C. After 3 h, the reaction is concentrated and the residue is chromatographed (40 g SiO2, 0% to 5% EtOAc/Hexanes) to yield 4-{4-[3-(2,6-Dichloro-phenyl)-5-isopropyl-3H-[1,2,3]triazol-4-ylmethoxy]-2-methyl-phenylethynyl}-benzoic acid methyl ester (38 mg, 64%). LC/MS m/e 534.2 (M+1).
