1H-NMR(400 MHz, D6-DMSO): δ=6.72(d, 1H, 1′-H), 7.35(d, 1H, 5″-H), 7.44(d, 1H, 2′-H), 7.50(d, 1H, 3″-H), 7.95(dd, 1H, 6″-H), 8.21(s, 1H, 5-H-oxazole). 26 mg (1.0 mmol) of 95% sodium hydride were given at 0° C. to a solution of 217 mg (1.00 mmol) 4-(4-[1,2,3]triazol-1-yl-butyl)-phenol in 2.0 ml N,N-dimethyl formamide and stirred for 30 min. 272 mg (1.00 mmol) 2-[2-(4-Chloro-2-fluoro-phenyl)-vinyl]-4-chloromethyl-oxazole dissolved in 1.0 ml N,N-dimethyl formamide were added at 0° C., stirring continued at 0° C. for 1 h and 12 h at room temperature thereafter. The mixture was quenched by 6 ml water, stirred for 1 h and the precipitate isolated by filtration. After washing with water, three times with cold ether and drying at 40° C. in vacuo, 350 mg (77%) 1-[4-(4-{2-[2-(E)-(4-chloro-2-fluoro-phenyl)-vinyl]-oxazol-4-ylmethoxy}-phenyl)-butyl]-1H-[1,2,3]triazole were obtained.
