A mixture of 4-[(3S,5R)-3-[(tert-butoxycarbonyl)amino]-5-(trifluoromethyl)piperidin-1-yl]-3-[({6-[2,6-difluoro-4-(1-hydroxy-1-methylethyl)phenyl]-5-fluoropyridin-2-yl}carbonyl)amino]-6,7-dihydro-5H-cyclopenta[b]pyridin-7-yl acetate (0.015 g, 0.020 mmol) in MeOH (0.8 mL), THF (0.8 mL) and 1.0 M aq. NaOH (0.8 mL, 0.8 mmol) was stirred at room temperature for 0.5 h. The solution was then concentrated under reduced pressure and the remaining aqueous phase was extracted with EtOAc. The organic extract was concentrated to dryness under reduced pressure. The residue was treated with 4.0 M HCl in dioxane (0.20 mL, 0.80 mmol) for 20 min. The reaction mixture was then concentrated under reduced pressure. The residue was dissolved in 4.5 mL of MeOH, neutralized with NH4OH solution, and purified by preparative LCMS (Waters SunFire™ C18 column, 19 mm×100 mm, 5 μm particle size, eluting with a gradient of MeCN/water containing 0.1% NH4OH, at flow rate of 30 mL/min.) to afford two separated diastereoisomers of the title compound as white powders.
