A solution of 3-(1-methyl-1H-pyrazol-3-yl)-5-(pyridin-3-yl)-1-((2-(trimethylsilyl)ethoxy)methyl)-1H-pyrazolo[3,4-c]pyridine (43.22 mg, 0.1063 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 232 as an off-white solid (23.7 mg, 81%). 1H NMR (400 MHz, DMSO) δ 13.74 (s, 1H), 9.33 (s, 1H), 9.19 (s, 1H), 8.67 (d, J=11.2 Hz, 2H), 8.56 (d, J=7.9 Hz, 1H), 7.85 (s, 1H), 7.63 (s, 1H), 6.82 (s, 1H), 4.01 (s, 3H). ESI MS m/z=277.0 (M+1)
