Reaction Steps

To a solution of 1,3-difluoropropanol (62 mg) in DMF (2.4 ml) was added 60% NaH (19 mg) at −10° C., followed by stirring at −10° C. for 0.5 hour. To this reaction mixture was added 2-{4-[5-(3-chloro-4-fluorophenyl)-1,2,4-oxadiazol-3-yl]-1H-indol-1-yl}acetamide (120 mg) at −10° C., followed by stirring at −10° C. for 3 hours. After adding water to the reaction solution, the reaction mixture was extracted with EtOAc, the organic layer was washed with saturated brine, dried over anhydrous MgSO4, and then filtered, and the filtrate was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (chloroform:CH3OH=100:0 to 95:5) to obtain 2-[4-(5-{3-chloro-4-[2-fluoro-1-(fluoromethyl)ethoxy]phenyl}-1,2,4-oxadiazol-3-yl)-1H-indol-1-yl]acetamide (76.9 mg) as a white solid.
