A mixture of 201 mg (0.86 mmol) 3-methyl-4-(2-[1,2,3]triazol-1-yl-ethoxymethyl)-phenol and 169 mg (0.52 mmol) cesium carbonate in 10 ml 2-butanone was stirred at 60° C. for 30 minutes, then 275 mg (0.86 mmol) 4-chloromethyl-2-[2-(4-trifluoromethylsulfanyl-phenyl)-vinyl]-oxazole and 143 mg (0.86 mmol) potassium iodide were added and stirring was continued overnight. After evaporation, the residue was mixed with aqueous NaOH (1N) and extracted with ethyl acetate. The combined extracts were dried, evaporated and the product purified on silica (ethyl acetate) to yield 280 mg (63%) of the title as a white solid melting at 102° C.
