Versuchsvorschrift

To a solution of 3-({[5-[(tert-butoxycarbonyl)amino]-2-(2,6-difluorophenyl)-1,3-thiazol-4-yl]carbonyl}amino)-4-[(3S,5R)-3-[(tert-butoxycarbonyl)amino]-5-(trifluoromethyl)piperidin-1-yl]-6,7-dihydro-5H-cyclopenta[b]pyridin-7-yl acetate (110.3 mg, 0.1384 mmol) in THF (1.0 mL) was added a 1.0 M NaOH solution in water (1.00 mL, 1.00 mmol) followed by MeOH (2.0 mL). The reaction mixture was stirred at room temperature for 1 h, and then concentrated under reduced pressure. To the resulting residue was added DCM (2.0 mL), followed by TFA (2.0 mL). The mixture was stirred at room temperature for 30 min., and then concentrated under reduced pressure. The resulting residue was purified using RP-HPLC (XBridge™ C18 column, eluting with a gradient of MeCN/water containing 0.1% NH4OH, at flow rate of 30 mL/min.) to afford both diastereoisomers of the title compound as white solids (9.3 mg for each, total yield 24%).
