Procedure

To a solution of 2,5-difluoro-N-[3-(3-{2-[(3-{[(trifluoroacetyl)amino]methyl}phenyl)-amino]-4-pyrimidinyl}pyrazolo[1,5-a]pyridin-2-yl)phenyl]benzamide (90 mg, 0.14 mmol) in THF (3 mL) and water (0.5 mL) was added LiOH.H2O (12 mg, 0.28 mmol). The solution was stirred at 50° C. for 2 h, then diluted with 25 mL EtOAc and washed with 1 M aqueous Na2CO3. The aqueous layer was extracted with EtOAc, and the combined organic layers were dried over Na2SO4, filtered, and concentrated. The crude product was purified by flash chromatography to generate 42 mg of the title compound as a yellow solid (0.08 mmol, 55% yield). 1H NMR (400 MHz, d6-DMSO): δ 10.66 (s, 1H), 9.55 (s, 1H), 8.85 (d, J=7.0 Hz, 1H), 8.54 (d, J=8.8 Hz, 1H), 8.27 (d, J=5.1 Hz, 1H), 8.05 (s, 1H), 7.87 (d, J=7.7 Hz, 1H), 7.77 (s, 1H), 7.35-7.59 (m, 7H), 7.11-7.23 (m, 2H), 6.97 (d, J=7.5 Hz, 1H), 6.51 (d, J=4.9 Hz, 1H), 3.72 (s, 2H). MS (ESI) m/z=548 [M+H]+.
