実験手順

A mixture of tert-butyl {(3S)-1-[3-({[6-(2,6-difluorophenyl)-5-fluoropyridin-2-yl]carbonyl}amino)-7-oxo-6,7-dihydro-5H-cyclopenta[b]pyridin-4-yl]piperidin-3-yl}carbamate (6.0 mg, 0.010 mmol) in DCM (0.05 mL) and TFA (0.052 mL, 0.68 mmol) was stirred at room temperature for 20 min. The solution was then concentrated 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 the title compound as a white powder (2.2 mg, 44%). LCMS calc. for C25H23F3N5O2 (M+H)+: m/z=482.2. Found: 482.3.
