Procedimiento

To a solution of tert-butyl N-[(3S)-1-[3-chloro-6-[6-(5-ethyl-3-pyridyl)pyrazolo[4,3-c]pyridin-1-yl]-2-pyridyl]-3-piperidyl]carbamate (0.0446 mmol; 23.8 mg) in Methanol (10 mL) was added hydrochloric acid, 4.0 M in 1,4-Dioxane (5 mL). The resulting mixture was stirred at room temperature overnight. The mixture was concentrated and the residue was purified by reverse phase HPLC to afford 117 (7.0 mg, 33%). 1H NMR (400 MHz, DMSO) δ 9.36-9.31 (s, 1H), 9.18-9.11 (m, 2H), 8.74-8.65 (s, 1H), 8.58-8.52 (d, J=1.9 Hz, 1H), 8.34-8.30 (s, 1H), 8.02-7.97 (d, J=8.4 Hz, 1H), 7.60-7.55 (d, J=8.4 Hz, 1H), 3.95-3.81 (dd, J=27.5, 10.2 Hz, 2H), 3.06-2.97 (t, J=10.2 Hz, 1H), 2.93-2.84 (t, J=9.5 Hz, 1H), 2.81-2.72 (m, 3H), 1.98-1.90 (d, J=12.6 Hz, 1H), 1.89-1.80 (d, J=13.3 Hz, 1H), 1.79-1.68 (d, J=12.9 Hz, 1H), 1.68-1.48 (s, 2H), 1.31-1.26 (t, J=7.6 Hz, 3H), 1.26-1.20 (m, 1H); MS (ESI) m/z: 434.2 [M+H]+
