Reaction Steps

To a solution of 2,6-difluoro-N-[3-(3-{2-[(3-{[methyl(trifluoroacetyl)amino]-methyl}phenyl)amino]-4-pyrimidinyl}pyrazolo[1,5-a]pyridin-2-yl)phenyl]benzamide (70 mg, 0.11 mmol) in THF (3 mL) and water (0.5 mL) was added LiOH.H2O (10 mg, 0.21 mmol). The solution was stirred at 50° C. for two h, then diluted with 25 mL DCM and washed with 1 M aqueous Na2CO3. The aqueous layer was extracted with DCM, and the combined organic layers were dried over Na2SO4, filtered, and concentrated. The crude product was purified by flash chromatography to generate 26 mg of the title compound as a yellow solid (0.05 mmol, 42% yield). 1H NMR (400 MHz, d6-DMSO): δ 10.95 (s, 1H), 9.52 (s, 1H), 8.86 (d, J=7.0 Hz, 1H), 8.52 (d, J=8.8 Hz, 1H), 8.27 (d, J=5.1 Hz, 1H), 8.02 (s, 1H), 7.83 (d, J=8.2 Hz, 1H), 7.73 (s, 1H), 7.46-7.62 (m, 4H), 7.36 (d, J=7.5 Hz, 1H), 7.12-7.28 (m, 4H), 6.92 (d, J=7.3 Hz, 1H), 6.53 (d, J=5.3 Hz, 1H), 3.59 (s, 2H), 2.26 (s, 3H). MS (ESI) m/z=562 [M+H]+.
