Procedure

A mixture of 3-amino-4-{(3S,5R)-3-[(tert-butoxycarbonyl)amino]-5-methylpiperidin-1-yl}-6,7-dihydro-5H-cyclopenta[b]pyridin-7-yl acetate (13.0 mg, 0.032 mmol), 3-[(tert-butoxycarbonyl)amino]-6-(2,6-difluorophenyl)-5-fluoropyridine-2-carboxylic acid (14.2 mg, 0.039 mmol), HATU (30.5 mg, 0.080 mmol) in DMF (0.09 mL) and DIPEA (0.019 mL, 0.096 mmol) was stirred at room temperature for 16 h. The reaction 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 (14.2 mg, 59%). LCMS calc. for C38H46F3N6O7 (M+H)+: m/z=755.3. Found: 755.1.
