A round bottom flask was mixed with 4-chloro-3-(3-{[5-cyano-2-propyl-4-(trifluoromethyl)-1H-indol-1-yl]methyl}-1,2,4-oxadiazol-5-yl)benzoyl chloride (Example 295B) (0.037 g, 0.07 mmol) and Me2NH (2.0 mL), and THF (5.0 mL). The mixture was stirred at rt for 2 h and concentrated to dryness. The resulting solid was crystallized with Et2O, filtered in vacuo and dried under high vacuum to afford a pure solid (0.025 g, 66% yield): MS (ES) m/z 515 (M+).
