Procedure

[1-Benzyl-7-(3-chloro-4-fluorophenyl)-1H-indol-3-yl](oxo)acetic acid was prepared from ethyl 2-[1-benzyl-7-(3-chloro-4-fluorophenyl)-1H-indol-3-yl]-2-oxoacetate (0.139 g, 0.319 mmol), and potassium hydroxide (0.076 g, 1.35 mmol) in THF (2.5 mL) and water (2.5 mL) following the procedure described in Step 4 of Example 5. Following work-up, and trituration of the residue with hexane, a solid was obtained. Drying for 12 hours at 82° C. yielded the title compound as a yellow solid (0.0836 g, 64%), mp: 153-156° C. Mass spectrum (−ESI, [M−H]−) m/z 406; 1HNMR (500 MHz, DMSO-d6): δ 13.8-14.2 (br s, 1H), 8.65 (s, 1H), 8.35 (m, 1H), 7.3-7.35 (m, 2H), 7.05-7.2 (m, 5H), 7.0 (s, 1H, J=7.1 Hz), 6.35 (d, 2H, J=6.9 Hz), 5.35 (d, 1H, J=16.6 Hz), and 5.15 ppm (d, 1H, J=16.6 Hz).
