Reaction Steps

4-(4-[1,2,3]Triazol-1-yl-butyl)-phenylamine (0.304 g, 1 mmol) is dissolved in anhydrous N,N-dimethylformamide (5 ml) followed by the addition of sodium hydride (0.024 g, 1 mmol). After stirring for 15 min at room temperature 4-chloromethyl-2-[2-(4-trifluoromethoxy-phenyl)-vinyl]-oxazole (0.324 g, 1.5 mmol) is added and the mixture stirred for 16 h at 80° C. Ethyl acetate (25 ml) is added, the mixture is washed with brine, dried over sodium sulfate and concentrated in vacuo. After flash column chromatography (ethyl acetate/hexanes 1:1->2:1) [4-(4-[1,2,3]triazol-1-yl-butyl)-phenyl]-{2-[2-(4-trifluoromethoxy-phenyl)-vinyl]-oxazol-4-ylmethyl}-amine 1 can be isolated as a yellow solid. Yield 0.14 g (29%); m.p. 103–105° C.
