Trifluoroacetic acid (0.25 mL, 3.24 mmol) was added to a suspension of 1,1-dimethylethyl(2S)-2-{[(2-{[({4-chloro-3-[(3-chloro-5-cyanophenyl)oxy]-2-fluorophenyl}methyl)amino}carbonyl]-1H-indol-5-yl)amino]carbonyl}-1-pyrrolidinecarboxylate (0.013 g, 0.020 mmol) in dichloromethane (1 mL). The resulting solution was stirred at RT for 1 h. The solvent was evaporated to give the title compound (0.013 g, 98%) an off-white solid. 1H NMR (400 MHz, DMSO-d6): δ ppm 11.67 (s, 1H), 10.38 (s, 1H), 9.24 (s, 1H), 9.02 (s, 1H), 8.66 (s, 1H), 7.95 (s, 1H), 7.81 (s, 1H), 7.46-7.55 (m, 2H), 7.36-7.44 (m, 1H), 7.28 (dd, 1H), 7.15 (d, 1H), 4.57 (s, 2H), 4.30 (m, 1H), 3.28 (m, 2H), 1.75-2.14 (m, 4H). MS: m/z 566 (M).
