Versuchsvorschrift

To a solution of 2-propyl-4-(trifluoromethyl)-1H-indole-5-carbonitrile (Example 153A) (0.100 g, 0.396 mmol) in anhydrous acetonitrile (20 mL) was added Cs2CO3 (1.30 g, 4.00 mmol) and 3-[3-(chloromethyl)-1,2,4-oxadiazol-5-yl]-2-(methylthio)pyridine (0.170 g, 0.594 mmol). The mixture was heated under N2, for 2 h. Upon cooling, the mixture was partitioned between EtOAc and water. The organic phase was separated, dried (MgSO4) and concentrated in vacuo. The residue was purified by flash chromatography (0-20% EtOAc-hexanes gradient) to afford a pure product (0.152 g, 84% yield): MS (ES) m/z 458 (M+).
