실험 절차

To a solution of 2-{4-[5-(4-fluoro-3-methylphenyl)-1,2,4-oxadiazol-3-yl]-1H-indol-1-yl}acetamide (100 mg) and (2R)-1,1,1-trifluoropropane-2-ol (109 mg) in DMF (3 ml) was added 60% NaH (17 mg) at 0° C., followed by stirring at 80° C. for 4 hours. The reaction solution was added with water (15 ml) to complete the reaction, filtered, and then dried. The obtained powder was purified by silica gel column chromatography (chloroform:CH3OH=100:0 to 95:5), and crystallized with diisopropyl ether to obtain 2-[4-(5-{3-methyl-4-[(1R)-2,2,2-trifluoro-1-methylethoxy]phenyl}-1,2,4-oxadiazol-3-yl)-1H-indol-1-yl]acetamide (70 mg) as a pale yellow solid.
