The resulting reaction mixture was stirred at room temperature for 24 hours. The reaction mixture was concentrated and the residue was purified by Mass Directed Auto Prep to afford ethyl N-{2-[7-(5-{3-chloro-4-[(1-methylethyl)oxy]phenyl}-1,2,4-oxadiazol-3-yl)-1H-indol-3-yl]ethyl}glycinate (D86) (132 mg) as a yellow solid. MS (ES): C25H27ClN4O4 requires 482; found 483.2 (M+H+).
