Reaction Steps

4-{1-[(2,2-dimethyl-1,3-dioxolan-4-yl)methyl]-1H-pyrazol-4-yl}-2-(isoquinolin-5-yl)furo[2,3-c]pyridin-7-amine (25.0 mg, 0.0566 mmol) was dissolved in MeOH (0.5 mL, 10 mmol) and HCl (4 M in 1,4-dioxane, 0.30 mL, 1.2 mmol) was added. The reaction stirred at RT for 16 h. The product mixture was then concentrated in vacuo to a solid. Purification by flash chromatography (0 to 10% 7 N NH3/MeOH:EtOAc) afforded 1 mg (4%) of the title compound. 1H NMR (400 MHz, CD3OD) δ 9.35 (s, 1 H), 8.59 (d, J=6.06 Hz, 1 H), 8.51 (d, J=6.06 Hz, 1H), 8.37 (dd, J=7.33, 1.26 Hz, 1H), 8.26 (d, J=8.34 Hz, 1H), 8.12 (s, 1H), 7.94 (d, J=3.79 Hz, 2H), 7.81-7.89 (m, 1H), 7.54 (s, 1H), 4.40 (dd, J=14.02, 4.17 Hz, 1H), 4.19-4.27 (m, 1H), 4.01-4.12 (m, 1H), 3.52-3.61 (m, 2H); MS (ESI): 402.15 [M+H]+; HPLC tR=0.79 min (TOF: polar—3 min).
