In a 50 mL round bottom flask was added 3-(2-fluorophenyl)-1-(tetrahydro-2H-pyran-2-yl)-5-(1-(tetrahydro-2H-pyran-2-yl)-1H-imidazol-5-yl)-1H-pyrazolo[3,4-c]pyridine (150 mg, 0.33 mmol) and 4 N HCl— dioxane (5 mL). The mixture was stirred at 25° C. for 2 h. The solvent was distilled off. The crude product was purified via reverse phase HPLC eluting with 35% CH3CN in aqueous 10 mmol NH4HCO3 solution to afford 218 as a white solid (20 mg, 21%). 1H NMR (500 MHz, DMSO) δ 13.93 (s, 1H), 12.21 (s, 1H), 9.05 (s, 1H), 8.20 (s, 1H), 7.86 (t, J=7.0, 1H), 7.71 (s, 1H), 7.62 (s, 1H), 7.56-7.54 (m, 1H), 7.46 (t, J=10.0, 1H), 7.41 (t, J=7.5, 1H). ESI MS m/z=280 (M+1)
