実験手順

Sodium hydroxide (30 mg) was added to a solution of ethyl 3-(4-fluoro-7-{5-[6-[(1-methylethyl)oxy]-5-(methyloxy)-3-pyridinyl]-1,2,4-oxadiazol-3-yl}-1H-indol-3-yl)propanoate (D50) (157 mg) in THF (3 mL) and water (3 mL). The reaction mixture was stirred at 90° C. for 1 hour. Then 0.5 M HCl 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 3-(4-fluoro-7-{5-[6-[(1-methylethyl)oxy]-5-(methyloxy)-3-pyridinyl]-1,2,4-oxadiazol-3-yl}-1H-indol-3-yl)propanoic acid (E25) (110 mg) as a white solid. δH (DMSO-d6, 400 MHz): 1.35 (6H, d), 2.62 (2H, t), 3.06 (2H, t), 3.95 (3H, s), 5.42 (1H, m), 6.99 (1H, dd), 7.26 (1H, d), 7.92 (2H, m), 8.67 (1H, d), 11.07 (1H, s), 12.14 (1H, br s). δF (DMSO-d6, 376 MHz): −118.8. MS (ES): C22H21FN4O5 requires 440; found 441.2 (M+H+).
