実験手順
A mixture of 3-({[5-[(tert-butoxycarbonyl)amino]-2-(2,6-difluoro-3-methoxyphenyl)-1,3-thiazol-4-yl]carbonyl}amino)-4-{(3S)-3-[(tert-butoxycarbonyl)amino]piperidin-1-yl}-6,7-dihydro-5H-cyclopenta[b]pyridin-7-yl acetate (3.2 mg, 0.0042 mmol), MeOH (50 μL), THF (25 μL) and 1.0 M aq. NaOH (27 μL, 0.027 mmol) was stirred at room temperature for 20 min. The organic solvents were removed under reduced pressure to give a crude intermediate, which was dissolved in DCM (0.04 mL), and then TFA (0.043 mL, 0.56 mmol) was added. The reaction mixture was stirred at room temperature for 20 min. After concentration under reduced pressure, the residue was diluted with MeOH, filtered and purified by preparative LC-MS (XBridge™ preparative C18 5 μm OBD™ column, 30×10 mm, 60 mL/min., eluting with a gradient of MeCN and water with 0.1% NH4OH) to give both diastereoisomers of the title compound as white powders. On analytical HPLC (Waters SunFire™ C18, 2.1×50 mm, 5 μm; flow rate 3 mL/min.; injection volume 2 μL; gradient from 2 to 80% B in 3 minutes (A=water with 0.025% TFA, B=MeCN)) the diastereoisomers had the following properties:
