실험 절차

To a solution 4-{5-[3-(trifluoromethyl)-4-(2,2,2-trifluoro-1-methylethoxy)phenyl]-1,2,4-oxadiazol-3-yl}-1H-indole (100 mg) in AcOH (3 ml) was added portionwise sodium cyanoboroate (29 mg). The reaction mixture was stirred at room temperature for 2 hours. The reaction mixture was diluted with water, alkalified with a 1M aqueous NaOH solution, and extracted with EtOAc. The organic layer was washed with saturated brine, dried over anhydrous MgSO4, and then filtered, the filtrate was concentrated, and the residue was purified by silica gel column chromatography (n-hexane:EtOAc=90:10 to 75:25), and washed with n-hexane to obtain 4-{5-[3-(trifluoromethyl)-4-(2,2,2-trifluoro-1-methylethoxy)phenyl]-1,2,4-oxadiazol-3-yl}indoline (90 mg) as a pale yellow solid.
