Procedure

To a solution of (R)-1-(6-(5-(pyridin-3-yl)-1-((2-(trimethylsilyl)ethoxy)methyl)-1H-pyrazolo[3,4-c]pyridin-3-yl)pyridin-2-yl)piperidin-3-ol (60 mg, 0.12 mmol) in dioxane 5 mL, was added 10% HCl (1 mL). The reaction mixture was heated at 70° C. for 2 h, and the reaction was monitored by LCMS. Upon completion of the reaction, the solvent was distilled off and the crude material was purified via reverse phase prep-HPLC eluting with 40% to 80% MeOH in aqueous 0.1% NH4OH to afford 271 as a yellow solid (20 mg, 45%). 1H NMR (400 MHz, DMSO) δ 9.34-9.28 (m, 1H), 9.21 (s, 1H), 8.62-8.58 (m, 1H), 8.45 (d, J=6, 1H), 7.67-7.64 (m, 1H), 7.54-7.50 (m, 1H), 7.45-7.44 (m, 1H), 6.87-6.85 (m, 1H), 4.96 (s, 1H), 4.36-4.34 (m, 1H), 4.15-4.12 (m, 1H), 3.63 (s, 1H), 3.16-3.12 (m, 1H), 3.01-2.97 (m, 1H), 1.99-1.97 (m, 1H), 1.85-1.83 (m, 1H), 1.60-1.56 (m, 1H), 1.52-1.45 (m, 1H). ESI MS m/z=373.7 (M+1)
