390 mg (0.62 mmol) of {3-[3-(2-methoxy-phenyl)-1-(toluene-4-sulfonyl)-1H-pyrrolo[2,3-b]pyridin-5-yl]-phenyl}-(3-trifluoromethyl-pyridin-2-yl)-methanol was dissolved in ethanol under gentle warming. The resulting solution was diluted with 2 M aqueous sodium hydroxide (16-30% v/v) and the resulting mixture was left at room temperature for 16 h. The pH was adjusted to 8 by addition of concentrated aqueous hydrochloric acid and the resulting solution was extracted three times with chloroform. The combined organic phases were dried over sodium sulfate and evaporated to afford 144 mg (0.30 mmol, 49%) of {3-[3-(2-methoxy-phenyl)-1H-pyrrolo[2,3-b]pyridin-5-yl]-phenyl}-(3-trifluoromethyl-pyridin-2-yl)-methanol as a yellow solid. 1H NMR (500 MHz, DMSO-d6) δ 11.93 (d, 1H), 8.86 (d, 1H), 8.49 (d, 1H), 8.20 (dd, 1H), 8.11 (d, 1H), 7.75 (s, br., 1H), 7.73 (d, 1H), 7.58 (d(m), 1H), 7.56 (d, 1H), 7.54 (dd, 1H), 7.40 (t, 1H), 7.32-7.29 (m, 2H), 7.15 (dd, 1H), 7.05 (dd, 1H), 6.23 (d, 1H), 6.09 (d, 1H), 3.82 (s, 3H); MS: m/z 476.1 (M+H+).
