Procedure
{2-[2-(4-Chloro-2-fluoro-phenyl)-vinyl]-oxazol-4-yl}-methanol (0.100 g, 0.39 mmol) is dissolved in anhydrous tetrahydrofuran (THF) (3 ml) followed by addition of sodium tert-butoxide (NaOtBu) (0.046 g, 0.47 mmol). After stirring for 15 min at r.t. 2-chloro-5-(4-[1,2,3]triazol-1-yl-butyl)-pyrimidine (0.085 g, 0.36 mmol) is added slowly and stirred for further 3 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/methanol 98:2) 2-{2-[2-(4-chloro-2-fluoro-phenyl)-vinyl]-oxazol-4-ylmethoxy}-5-(4-[1,2,3]triazol-1-yl-butyl)-pyrimidine is obtained as a colorless solid. Yield 0.125 g (77%).
