Procedure

2-(3-(1H-imidazol-2-yl)-1H-pyrazolo[3,4-b]pyridin-1-yl)acetic acid tert-butyl ester (977 mg) was dissolved in trifluoroacetic acid (TFA) (10 mL) and stirred at room temperature for 1 hr. The mixture was evaporated in vacuo to provide 2-(3-(1H-imidazol-2-yl)-1H-pyrazolo[3,4-b]pyridin-1-yl)acetic acid as a brown oil, which was used without further purification.
