25 mg (1.0 mmol) of 95% sodium hydride were given to a solution of 219 mg (1.0 mmol) 4-(2-[1,2,3]triazol-1-yl-ethoxymethyl)-phenol in 5 ml N,N-dimethylformamide and stirred for 15 min at room temperature. Then 254 mg (1.0 mmol) 2-[2-(4-chloro-phenyl)-vinyl]-4-chloromethyl-oxazole were added and stirring continued over night. The mixture was quenched with water, stirred for 1 h and the precipitate isolated by filtration. After washing with water, little methanol, ethyl acetate/heptane 2:1 and ether, and drying at 40° C. in vacuo, 341 mg (78%) 1-[2-(4-{2-[2-(E)-(4-chloro-phenyl)-vinyl]-oxazol-4-ylmethoxy}-benzyloxy)-ethyl]-1H-[1,2,3]triazole were obtained.
