Procedure

4-(6-(4-((R)-1-((R)-1-((R)-1-(4-methoxyphenyl)ethyl)-5-oxopyrrolidin-3-yl)ethoxy)pyrazolo[1,5-a]pyridin-6-yl)pyridin-3-yl)piperazine-1-carboxylate 6.20 (30 mg, 0.036 mmol) was dissolved in TFA (2.0 mL) and heated to 60° C. overnight. The reaction was concentrated to dryness (solvent exchange was performed with acetonitrile and toluene). The residue was passed through a polymer-supported bicarbonate column to provide (R)-4-((R)-1-((6-(5-(piperazin-1-yl)pyridin-2-yl)pyrazolo[1,5-a]pyridin-4-yl)oxy)ethyl)pyrrolidin-2-one 6.21, as the free base, and was used without further purification.
