Procedure
A mixture of 6-(1-(2,2,2-trifluoroethyl)-1H-pyrazol-4-yl)-1-((2-(trimethylsilyl)ethoxy)-methyl)-1H-pyrazolo[4,3-c]pyridine (800 mg, 2.02 mmol) and TFA (5 mL) in DCM (10 mL) was stirred at ambient temperature for 20 hours. The reaction mixture was concentrated under reduced pressure to afford 6-(1-(2,2,2-trifluoroethyl)-1H-pyrazol-4-yl)-1H-pyrazolo[4,3-c]-pyridine as a yellow oil (539 mg, 100%). MS (ESI) m/z: 268 [M+H]+.
