Procedure

The amide intermediate prepared as described above was treated with THF (6 mL), MeOH (6 mL) and 1.0 M aq. NaOH (7.39 mL, 7.39 mmol) at room temperature for 20 min. The volatile solvents were removed under reduced pressure. The residue was extracted with EtOAc (2 times). The combined organic phases were washed with brine, dried over Na2SO4, concentrated under reduced pressure to give an alcohol intermediate, tert-butyl ((3S,5R)-1-{3-[({6-[2,6-difluoro-4-(1-hydroxy-1-methylethyl)phenyl]-5-fluoropyridin-2-yl}carbonyl)amino]-7-hydroxy-6,7-dihydro-5H-cyclopenta[b]pyridin-4-yl}-5-methylpiperidin-3-yl)carbamate.
