To a solution of 116 mg (0.5 mmol) 1-(4-hydroxy-phenyl)-4-[1,2,3]triazol-1-yl-butan-1-one in 10 ml 2-butanone 98 mg (0.3 mmol) cesium carbonate was added and the mixture was stirred at 60° C. for 30 minutes. Then 152 mg (0.5 mmol) 4-chloromethyl-2-[(E)-2-(4-trifluoromethoxy-phenyl)-vinyl]-oxazole and 83 mg (0.5 mmol) potassium iodide were added and the mixture was stirred at 60° C. overnight. After removal of all volatiles in vacuo the residue was purified by column chromatography on silica (ethyl acetate) to give 4-[1,2,3]triazol-1-yl-1-(4-{2-[(E)-2-(4-trifluoromethoxy-phenyl)-vinyl]-oxazol-4-ylmethoxy}-phenyl)-butan-1-one. Yield: 200 mg (81%) white solid.
