Participants

Reaction Steps

tert-Butyl [(3S)-1-(3-amino-6,7-dihydro-5H-cyclopenta[b]pyridin-4-yl)piperidin-3-yl]carbamate (5.0 mg, 0.015 mmol), 6-(2,6-difluorophenyl)-5-fluoropyridine-2-carboxylic acid (4.6 mg, 0.018 mmol), HATU (14 mg, 0.038 mmol), DMF (0.035 mL) and DIPEA (5.8 mg, 0.045 mmol) were mixed together and stirred at room temperature for 1 h. The mixture was filtered, concentrated under reduced pressure and purified by preparative LC-MS (XBridge™ preparative C18 30×10 mm 5 μm OBD™ column, flow rate 60 mL/min., eluting with a gradient of MeCN and water with 0.15% NH4OH) to give the sub-title compound as a colorless gum (4.1 mg, 48%). LCMS calc. for C30H33F3N5O3 (M+H)+: m/z=568.3. Found: 568.1.
