Tetrahydrofuran → tert-butyl ((3S,5R)-1-{3-[({6-[2,6-difluoro-4-(tetrahydro-2H-pyran-3-yloxy)phenyl]-5-fluoropyridin-2-yl}carbonyl)amino]-7-hydroxy-6,7-dihydro-5H-cyclopenta[b]pyridin-4-yl}-5-methylpiperidin-3-yl)carbamate

Participants

Reaction Steps

The amide intermediate was treated with THF (0.7 mL), MeOH (0.7 mL) and 1.0 M aq. NaOH (0.74 mL, 0.74 mmol) at room temperature for 20 min. The volatile organic solvents were removed. The residue was extracted with EtOAc (2 times). The combined organic extracts were washed with brine, dried over Na2SO4, and concentrated to give an alcohol intermediate, tert-butyl ((3S,5R)-1-{3-[({6-[2,6-difluoro-4-(tetrahydro-2H-pyran-3-yloxy)phenyl]-5-fluoropyridin-2-yl}carbonyl)amino]-7-hydroxy-6,7-dihydro-5H-cyclopenta[b]pyridin-4-yl}-5-methylpiperidin-3-yl)carbamate.
