To a stirred solution of tert-butyl (3R)-1-(6-(5-(1-methyl-1H-pyrazol-4-yl)-1-(tetrahydro-2H-pyran-2-yl)-1H-pyrazolo[3,4-c]pyridin-3-yl)pyridin-2-yl)pyrrolidin-3-ylcarbamate (60.0 mg, 0.12 mmol) in anhydrous DCM (5.0 mL) and methanol (2.5 mL) was added 4M HCl in 1,4-Dioxane (4.0 mL). The reaction mixture was stirred at 60° C. under N2 for 18 h. Volatile solvent was evaporated in vacuo. The crude was redissolved in DMSO (1 mL) and was purified by reverse phase HPLC to give 189 as a white solid (25.5 mg, 58.4%). 1H NMR (400 MHz, DMSO) δ 9.02 (s, 1H), 8.71 (s, 1H), 8.13 (s, 1H), 7.87 (s, 1H), 7.59 (t, J=7.9 Hz, 1H), 7.36 (d, J=7.4 Hz, 1H), 6.41 (d, J=8.4 Hz, 1H), 3.91 (s, 3H), 3.81-3.64 (m, 4H), 3.63-3.52 (m, 2H), 2.17 (dt, J=12.3, 6.5 Hz, 2H), 1.88-1.75 (m, 2H).
