Reaction Steps

{1-Benzyl-4-[4-(trifluoromethoxy)phenyl]-1H-indol-3-yl}(oxo)acetic acid was prepared from ethyl {1-benzyl-4-[4-(trifluoromethoxy)phenyl]-1H-indol-3-yl}(oxo)acetate (0.167 g, 0.357 mmol), and potassium hydroxide. (0.103 g, 1.84 mmol) in THF (5 mL) and water (5 mL), according to the procedure described in Step 4 of Example 5. Drying for 12 hours at 90° C. furnished the title compound as a light yellow solid (0.131 g, 83%), mp: 167-169° C. (dec.). Mass spectrum (+ESI, [M+H]+) m/z 440; 1HNMR (500 MHz, DMSO-d6): δ 13.5-14.0 (br s, 11H), 8.65 (s, 1H), 7.65 (d, 1H, J=8.2 Hz), 7.25-7.4 (m, 10H), 7.15 (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, 65.57; 3.50; N, 3.16.
