실험 절차

Sodium hydroxide (19 mg) was added to a solution of ethyl 1-{[6-(5-{5-chloro-6-[(1-methylethyl)oxy]-3-pyridinyl}-1,2,4-oxadiazol-3-yl)-1H-indol-3-yl]methyl}-4-piperidinecarboxylate (D103) (134 mg) in iPrOH (4 mL) and water (4 mL). The resulting mixture was heated at 70° C. for 40 mins. Then 0.5 M HCl solution was added until pH was about 6. The solvent was concentrated, and the residue was dissolved in water. The precipitated solid was purified by Mass Directed Auto Prep to afford 1-{[6-(5-{5-chloro-6-[(1-methylethyl)oxy]-3-pyridinyl}-1,2,4-oxadiazol-3-yl)-1H-indol-3-yl]methyl}-4-piperidinecarboxylic acid (E78) (118 mg) as a pale red-white solid. δH (DMSO-d6, 400 MHz): 1.37 (6H, d), 1.55 (2H, m), 1.77 (2H, m), 2.01 (2H, m), 2.18 (1H, m), 2.85 (2H, m), 3.67 (2H, m), 5.46 (1H, m), 7.46 (1H, s), 7.73 (1H, dd), 7.81 (1H, d), 8.14 (1H, s), 8.56 (1H, d), 8.94 (1H, d), 11.37 (1H, s), 12.02 (1H, br s). MS (ES): C26H26ClN6O4 requires 495; found 496.2 (M+H+).
