Procedure

1-Benzyl-5-[3-(trifluoromethoxy)phenyl]-1H-indol-3-yl}(oxo)acetic acid was prepared from ethyl {1-benzyl-5-[3-(trifluoromethoxy)phenyl]-1H-indol-3-yl}(oxo)acetate (1.1 g, 2.4 mmol), and potassium hydroxide (0.44 g, 7.8 mmol) in THF (25 mL) and water (25 mL), according to the procedure described in Step 4 of Example 5. Crystallization from methylene chloride/hexane yielded the title compound as a light yellow solid (0.596 g, 54%), mp: 141-142° C. Mass spectrum (+ESI, [M+H]+) M/z 440; 1HNMR (500 MHz, DMSO-d6): δ13.8-14.2 (br s, 1H), 8.75 (s, 1H), 8.45 (s, 1H), 7.7 (m, 2H), 7.6 (t, 3H, J=4.4 Hz), 7.25-7.35 (m, 6H), and 5.65 ppm (s, 2H). Elemental Analysis for C24H16F3NO4: Calculated: C, 65.61; H, 3.67; N, 3.19. Found: C, 65.41; H, 3.39; N, 3.09.
