Procedure

To a solution of methyl 5-((R)-2-(1-((R)-3-amino-2-methylpropyl)-5-fluoro-2-oxo-1,2-dihydropyridin-3-yl)pyrrolidin-1-yl)pyrazolo[1,5-a]pyrimidine-3-carboxylate (65 mg, 0.15 mmol) in THF/MeOH (6 mL/2 mL) was added lithium hydroxide (455 μL, 0.91 mmol). The reaction was stirred at 70° C. for 3 hours, then quenched with hydrogen chloride (910 μL, 0.91 mmol). The solvent was removed under reduced pressure and the residue was dried under high vacuum. To the resulting crude residue was added DMF (10 mL), HATU (115 mg, 0.30 mmol) and N-ethyl-N-isopropylpropan-2-amine (78 mg, 0.61 mmol). The reaction was stirred for 3 hours, and the solvent was removed under reduced pressure. The residue was purified by silica column chromatography, eluting with 10% MeOH/EtOAc to afford the title compound (6.0 mg, 10% yield). MS (apci) m/z=397.3 (M+H).
