To 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 (150 mg, 0.3 mmol) in DCM (5 mL) was added diethylaminosulfur trifluoride (DAST, 0.12 mL, 0.9 mmol). The mixture was stirred at room temperature for 1 hour, which was monitored by LCMS. After completion of the reaction, it was concentrated under reduced pressure to afford 1-(6-(4-fluoroazepan-4-yl)pyridin-2-yl)-6-(1-methyl-1H-pyrazol-4-yl)-1H-pyrazolo[4,3-c]pyridine as a light yellow oil (130 mg, 87%). MS (ESI) m/z: 493 [M+H]+.
