Procedure

{1-Benzyl-7-[4-(trifluoromethoxy)phenyl]-1H-indol-3-yl}(oxo)acetic acid was prepared from ethyl {1-benzyl-7-[4-(trifluoromethoxy)phenyl]-1H-indol-3-yl}(oxo)acetate (0.318 g, 0.680 mmol), and potassium hydroxide (0.123 g, 2.19 mmol) in THF (3 mL) and water (3 mL) according to the procedure described in Step 4 of Example 5. Purification by crystallization from isopropanol and drying for 12 hours at 80° C. yielded the title compound as a white solid. (0.171 g, 57%), mp: 177-178° C. Mass spectrum (−ESI, [M−H]−) m/z 438; 1HNMR (500 MHz, DMSO-d6): δ 13.8-14.2 (br s, 1H), 8.65 (s, 1H), 8.35 (dd, 1H, J=7.9 Hz and 1.1 Hz), 7.35 (t, 1H, J=7.6 Hz), 7.2-7.25 (m, 4H), 7.1 (t, 1H, J=7.3 Hz), 7.0-7.05 (m, 3H), 6.25 (d, 2H, J=7.3 Hz), and 5.6 ppm (s, 2H). Elemental Analysis for C24H16F3NO4: Calculated: C, 65.61; H, 3.67; N, 3.19. Found: C, 65.48; H, 3.44; N, 3.16.
