222 mg (0.397 mmol) of 2-amino-3-fluoro-5-[3-(2-methoxy-phenyl)-1-(toluene-4-sulfonyl)-1H-pyrrolo[2,3-b]pyridin-5-yl]-N,N-dimethyl-benzamide was dissolved in 5 mL methanol and 200 μL of a 50% w/v potassium hydroxide aqueous solution was added. The mixture was stirred at room temperature for 5.5 hours and then neutralized with acetic acid. The material was filtered through a 0.45 μm syringe filter and purified by mass-triggered reverse phase HPLC in a gradient of acetonitrile and water (containing 0.1% formic acid). The clean fractions were lyophilized to afford 100 mg (0.247 mmol, 62% yield) of 2-amino-3-fluoro-5-[3-(2-methoxy-phenyl)-1H-pyrrolo[2,3-b]pyridin-5-yl]-N,N-dimethyl-benzamide as an off-white powder. 1H NMR (500 MHz, DMSO-d6) δ 11.79 (d, 1H), 8.41 (d, 1H), 8.02 (d, 1H), 7.65 (d, 1H), 7.56 (dd, 1H), 7.45 (dd, 1H), 7.22 (t, 1H), 7.15 (d, 1H), 7.07 (d, 1H), 6.99 (t, 1H), 5.17 (s, 2H), 3.75 (s, 3H), 2.90 (s, br., 6H); MS: m/z 405.1 (M+H+).
