Procedure

A mixture of 3-amino-4-{(3S)-3-[(tert-butoxy carbonyl)amino]piperidin-1-yl}-6,7-dihydro-5H-cyclopenta[b]pyridin-7-yl acetate (13.6 mg, 0.035 mmol), 6-(2,6-difluoro-3-methoxyphenyl)-5-fluoropyridine-2-carboxylic acid (9.0 mg, 0.032 mmol), HATU (30.2 mg, 0.080 mmol) in DMF (0.07 mL) and DIPEA (0.017 mL, 0.095 mmol) was stirred at room temperature for 16 h. The mixture was diluted with MeOH 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 sub-title compound as a white powder (5.0 mg, 24%). LCMS calc. for C33H37F3N5O6 (M+H)+: m/z=656.3. Found: 656.3.
