{2-[2-(4-Trifluoromethoxy-phenyl)-vinyl]-oxazol-4-yl}-methanol (0.097 g, 0.34 mmol) is dissolved in anhydrous tetrahydrofuran (THF) (4 ml) followed by addition of sodium tert-butoxide (NaOtBu) (0.040 g, 0.41 mmol). After stirring for 15 min at r.t. 2-chloro-5-(4-[1,2,3]triazol-1-yl-butyl)-pyrimidine (0.090 g, 0.38 mmol) is added slowly and stirred for further 1.5 h at r.t. Ethyl acetate (20 ml) is added; the mixture is washed with saturated ammonium chloride (NH4Cl), dried over MgSO4 and concentrated in vacuo. After flash column chromatography (ethyl acetate) 5-(4-[1,2,3]triazol-1-yl-butyl)-2-{2-[2-(4-trifluoromethoxy-phenyl)-vinyl]-oxazol-4-ylmethoxy}-pyrimidine is obtained as a colorless solid. Yield 0.104 g (63%).
