실험 절차

To a solution of 4-(trifluoromethyl)-2-(3,3,3-trifluoropropyl)-1H-indole-5-carbonitrile (Example 302A) (0.200 g, 0.653 mmol) in anhydrous acetonitrile (25 mL) was added Cs2CO3 (0.851 g, 0.2.612 mmol) and 3-(chloromethyl)-5-(3,5-difluorophenyl)-1,2,4-oxadiazole (0.226 g, 0.979 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 (0.078 g, 24% yield): MS (ES) m/z 500 (M+).
