A mixture of 4-{(3S)-3-[(tert-butoxycarbonyl)amino]piperidin-1-yl}-3-({[6-(2,6-difluorophenyl)-5-fluoropyridin-2-yl]carbonyl}amino)-6,7-dihydro-5H-cyclopenta[b]pyridin-7-yl acetate (174 mg, 0.28 mmol), MeOH (0.7 mL), THF (0.7 mL) and 1.0 M aq. NaOH (1.1 mL, 1.1 mmol) was stirred at room temperature for 20 min. The organic solvents were removed under reduced pressure. The aqueous layer was diluted with EtOAc and NH4Cl (aq.), extracted with EtOAc twice. The combined organic layers were dried, filtered and concentrated under reduced pressure to give the sub-title compound (151 mg, 93%). LCMS calc. for C30H33F3N5O4 (M+H)+: m/z=584.2. Found: 584.2.
