To a solution of tert-butyl 1-(5-(5-(pyridin-3-yl)-1-(tetrahydro-2H-pyran-2-yl)-1H-pyrazolo[3,4-c]pyridin-3-yl)pyridin-3-yl)piperidin-4-ylcarbamate in methylene chloride (1.00 mL, 15.6 mmol) was added trifluoroacetic Acid (0.3109 mL, 4.036 mmol). The reaction was stirred at RT for 18 hours. The reaction was concentrated then submitted for rHPLC (reverse phase HPLC) to give 158 (10 mg, 33% yield). ESI MS m/z=372.1 (M+1). 1H NMR (400 MHz, DMSO) δ 9.39 (s, 1H), 9.24 (s, 1H), 8.72 (s, 1H), 8.61-8.52 (m, 3H), 8.42 (s, 1H), 7.83 (s, 1H), 7.55-7.48 (m, 1H), 3.85 (d, J=13.0 Hz, 2H), 2.98-2.76 (m, 3H), 1.91-1.81 (m, 2H), 1.42 (dd, J=20.7, 10.2 Hz, 2H)
