To a mixture of 3-{[(benzyloxy)carbonyl]amino}-7-(2-oxopiperidin-1-yl)quinoline-2-carboxylic acid (0.015 g, 0.036 mmol), tert-butyl [(3S,5R)-1-(3-aminopyridin-4-yl)-5-methylpiperidin-3-yl]carbamate (0.013 g, 0.043 mmol) and HATU (0.034 g, 0.089 mmol) in DMF (0.3 mL), DIPEA (0.019 mL, 0.11 mmol) was added. The mixture was stirred at room temperature for 2 h, then quenched with 5 mL of EtOAc and 3 mL of 1 M NaOH. The resulting layers were separated and the aqueous phase was extracted with EtOAc. The combined organic extracts were concentrated under reduced pressure, then purified by preparative HPLC (XBridge™ C18 column, eluting with a gradient of MeCN/water containing 0.1% NH4OH, at a flow rate of 60 mL/min.) to afford the sub-title compound (0.005 g, 20%). LCMS calc. for C39H46N7O6 [M+H]: m/z=708.3. found: 708.4.
