Vorschrift

Tert-butyl 4-(3-(5-(pyridin-3-yl)-1-(tetrahydro-2H-pyran-2-yl)-1H-pyrazolo[3,4-c]pyridin-3-yl)-1H-pyrazol-1-yl)piperidine-1-carboxylate (17.0 mg, 0.032 mmol) in Dioxane (5 mL) was treated with 4.0 M of Hydrogen chloride in 1,4-Dioxane (5 mL) overnight at room temperature. The reaction mixture was concentrated, and the residue was purified by reverse phase HPLC to afford 215 as an off-white solid (1.2 mg, 18%). 1H NMR (400 MHz, DMSO) δ 9.28 (s, 1H), 9.19 (s, 1H), 8.70-8.57 (m, 2H), 8.44 (d, J=7.6 Hz, 1H), 8.30 (s, 1H), 7.94 (s, 1H), 7.59-7.51 (m, 1H), 6.84 (s, 1H), 4.47 (s, 1H), 3.22 (d, J=12.7 Hz, 2H), 2.82 (t, J=12.0 Hz, 2H), 2.15 (d, J=11.5 Hz, 2H), 2.04 (d, J=9.0 Hz, 2H). ESI MS m/z=346.1 (M+1)
