Procedure

To a solution of [4-(5-{3-(trifluoromethyl)-4-[(1S)-2,2,2-trifluoro-1-methylethoxy]phenyl}-1,2,4-oxadiazol-3-yl)-1H-indol-1-yl]acetic acid (100 mg) in DMF (1 ml) was added CDI (39 mg), and after 30 min, methanesulfonamide (23 mg) and 2,3,4,6,7,8,9,10-octahydropyrimide[1,2-a]azepine (37 mg) were added thereto, followed by stirring at room temperature for 15 hours. The reaction mixture was added with water to complete the reaction. It was extracted with EtOAc, the obtained organic layer was washed with saturated brine, dried over anhydrous MgSO4, and then filtered, and the filtrate was concentrated. The residue was purified by silica gel column chromatography (chloroform:CH3OH=100:0 to 90:10) to obtain N-(methylsulfonyl)-2-[4-(5-{3-(trifluoromethyl)-4-[(1S)-2,2,2-trifluoro-1-methylethoxy]phenyl}-1,2,4-oxadiazol-3-yl)-1H-indol-1-yl]acetamide (56.4 mg) as a white solid.
