Procedure

To a mixture of 3-{[(benzyloxy)carbonyl]amino}-7-morpholin-4-ylquinoline-2-carboxylic acid (31 mg, 0.075 mmol), tert-butyl methyl [(3R,4S,5S)-1-(3-aminopyridin-4-yl)-5-methylpiperidine-3,4-diyl]biscarbamate (30 mg, 0.079 mmol) and HATU (92 mg, 0.24 mmol) in DMF (1.0 mL), DIPEA (90 μL, 0.52 mmol) was added. The reaction mixture was stirred at room temperature overnight. The mixture was then purified by preparative LCMS (pH=10 method; 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 yellow solid (30 mg, 51%). LCMS calc. for C40H49N8O8 (M+H)+: m/z=769.4. Found: 769.4.
