Procedure

A solution of tert-butyl 4-hydroxy-4-(6-(6-(1-methyl-1H-pyrazol-4-yl)-1H-pyrazolo[4,3-c]pyridin-1-yl)pyridin-2-yl)azepane-1-carboxylate (200 mg, 0.41 mmol) in a solution of HCl in MeOH (2.0 M, 10 mL) was stirred at room temperature for 1 hour, which was monitored by LCMS. After completion of the reaction, the reaction mixture was concentrated under reduced pressure. The crude was purified by reverse phase preparative HPLC to afford 230 as a light yellow solid (30 mg, 31%). 1H NMR (500 MHz, CDCl3) δ (ppm) 9.06 (s, 1H), 8.85 (s, 1H), 8.26 (s, 1H), 8.06 (s, 1H), 8.03 (s, 1H), 7.88-7.89 (d, J=4.5 Hz, 2H), 7.56-7.58 (t, J=9 Hz, 1H), 4.00 (s, 3H), 3.31-3.38 (m, 2H), 3.10-3.13 (t, J=13 Hz, 1H), 2.81-2.83 (t, J=12 Hz, 1H), 2.37-2.46 (m, 3H), 2.10-2.17 (m, 4H), 1.82-1.85 (t, J=14.5 Hz, 1H); MS (ESI) m/z: 390 [M+H]+.
