To a solution of (R)-ethyl 5-(2-(1-(3-aminopropyl)-5-fluoro-2-oxo-1,2-dihydropyridin-3-yl)pyrrolidin-1-yl)pyrazolo[1,5-a]pyrimidine-3-carboxylate (0.11 g, 0.26 mmol) in 3:1 THF/MeOH (8 mL) was added LiOH (1 N, 1.5 mL, 1.5 mmol), and the reaction mixture was heated at 70° C. for 20 hours. After cooling, the reaction mixture was treated with MeOH, acidified with 1N HCl (1.5 mL), and concentrated to afford the desired product (0.1 g, 100% yield). MS (apci) m/z=401.1 (M+H).
