실험 절차

4-Chloro-2-ethyl-1H-benzimidazole-5-carbonitrile (0.014 g, 0.068 mmol), Cs2CO3 (0.033 g, 0.102 mmol), and 3-(chloromethyl)-5-[3-(trifluoromethyl)phenyl]-1,2,4-oxadiazole (0.027 g, 0.102 mmol) were combined in DMF (10 mL) and heated to 90° C. for 30 min. The cooled reaction mixture was partitioned between Et2O and water. The organic portion was washed with brine, dried over Na2SO4, filtered, and concentrated in vacuo. Purification (SiO2, EtOAc/hexanes) afforded the title compound (0.0037 g): MS (ESI) m/z 432 (M+1).
