Participants

Reaction Steps

To a solution of tert-butyl 2-(3-carbamoyl-1H-pyrazolo[3,4-c]pyridin-1-yl)acetate (663 mg, 2.40 mmol) in CH2Cl2 (20 mL) was added TFA (10 mL, 130 mmol), and the resulting mixture was stirred at RT for 6 h. The reaction mixture was concentrated in vacuo, the residual solid was suspended in methanol and volatiles were removed again in vacuo to give the title compound.
