Versuchsvorschrift

To a solution of 2,2,2-trifluoro-N-[3-(3-{2-[(2-methyl-1,2,3,4-tetrahydro-7-isoquinolinyl)amino]-4-pyrimidinyl}pyrazolo[1,5-a]pyridin-2-yl)phenyl]acetamide (290 mg, 0.53 mmol) in tetrahydrofuran (2 mL) and deionized water (2 mL) was added LiOH.H2O (34 mg, 0.80 mmol). The reaction was heated to 50° C. for 3 h, and then diluted with 10 mL DCM. The aqueous layer was extracted with EtOAc, and the combined organic layers were dried over Na2SO4, filtered, and concentrated to generate the title compound in 92% yield (219 mg, 0.49 mmol). 1H NMR (400 MHz, d6-DMSO) δ 9.41 (s, 1H), 8.79 (d, J=6.8 Hz, 1H), 8.52 (bd, 1H), 8.21 (d, J=5.3 Hz, 1H), 7.53 (s, 1H), 7.41-7.46 (m, 2H), 7.08-7.15 (m, 2H), 7.00 (d, J=8.2 Hz, 1H), 6.80 (s, 1H), 6.67 (t, J=7.7 Hz, 1H), 6.49 (d, J=5.3 Hz, 1H), 5.25 (s, 2H), 3.42 (s, 2H), 2.76 (t, J=5.7 Hz, 2H), 2.58 (t, J=5.7 Hz, 2H), 2.32 (s, 3H). MS (ESI) m/z=448 [M+H]+.
