Procedure

To a solution of (±)-ethyl 2-(1-(5-cyano-1H-benzo[d]imidazol-2-yl)-2,2,2-trifluoro-1-(5-methoxy-7-methyl-1H-indol-4-yl)ethoxy)-2-fluoroacetate (Example 35-F) (60 mg, 0.119 mmol) in THF (1.0 mL), water (1.0 mL) and MeOH (0.20 mL) was added LiOH (25 mg, 0.595 mmol) and this mixture was stirred for 16 hr at room temperature. The reaction was partitioned between EtOAc and cold 1N HCl solution and the layers separated and the organic layer was washed with brine, dried over sodium sulfate, filtered, and concentrated. This material was purified with FCC eluting with dichloromethane/MeOH (0-10%) to afford the title compound. 1H NMR (400 MHz, DMSO-d6) δ ppm 11.03 (br.s., 1H) 10.96 (br.s, 1H), 8.17-8.34 (br.s., 1H) 7.78-7.97 (br.s., 1H) 7.53-7.59 (m, 1H) 7.19-7.29 (m, 1H) 7.00-7.02 (br.s, 1H) 6.74-6.79 (br.s., 1H), 6.65 (s., 1H), 4.87-5.37 (m, 1H) 3.01 (s, 3H) 2.46 (s, 3H). HRMS calcd. for C22H16F4N4O4 (M+H)+ 477.1141. found 477.1154.
