A mixture of 3-(1H-pyrazol-3-yl)-5-(pyridin-3-yl)-1-(tetrahydro-2H-pyran-2-yl)-1H-pyrazolo[3,4-c]pyridine (29.36 mg, 0.08476 mmol) in 4.0 M of Hydrogen chloride in 1,4-Dioxane (5 mL) and 1,4-Dioxane (5 mL) was stirred at room temperature overnight. The reaction mixture was concentrated and the residue was purified by reverse phase HPLC to afford 193 as an off-white solid (10.2 mg, 45.9%). 1H NMR (400 MHz, DMSO) δ 13.71 (s, 1H), 13.14 (s, 1H), 9.23 (d, J=31.1 Hz, 2H), 8.72-8.55 (m, 2H), 8.43 (s, 1H), 7.91 (s, 1H), 7.53 (dd, J=8.0, 4.8 Hz, 1H), 6.84 (s, 1H); ESI MS m/z=263.0 (M+1)
