Procedure
Tert-butyl 1H-pyrazolo[4,3,b]pyridin-1-ylacetate (Preparation 189, 220 mg, 0.944 mmol) was dissolved in HCl (4 mL, 4.0 M in 1,4 dioxane) and stirred under nitrogen at room temperature for 4 hours. The mixture was evaporated in vacuo and the residue was triturated with anhydrous diethyl ether to afford the title compound as an off white solid in 60% yield, 120 mg.
