Procedure

LiOH.H2O (43 mg, 1 mmol) in water (2 mL) was added to a stirred solution of (R)-methyl 4-((tert-butoxycarbonyl)amino)-1-(5-(2-(2,5-difluorophenyl)pyrrolidin-1-yl)pyrazolo[1,5-a]pyridine-3-carbonyl)piperidine-4-carboxylate (120 mg, 0.2 mmol) in THF (6 mL), MeOH (2 mL) and water (2 mL) at 20-35° C. The reaction mixture was stirred for 6 h; thereafter it was concentrated under reduced pressure to afford a crude product. The crude product thus obtained was diluted with cold water, acidified with 2N aqueous HCl solution, extracted with ethyl acetate, dried over anhydrous sodium sulphate and concentrated under reduced pressure to afford 100 mg of the title compound as a pale green solid. MS (ESI): m/z 570.2 (M+H).
