Procedure

To a mixture of 3-{[(benzyloxy)carbonyl]amino}-7-(4-methylpiperazin-1-yl)quinoline-2-carboxylic acid (9.9 mg, 0.024 mmol), tert-butyl [(3R,4S,5S)-1-(3-aminopyridin-4-yl)-5-methyl-4-(1H-1,2,3-triazol-1-yl)piperidin-3-yl]carbamate (8.0 mg, 0.021 mmol), and HATU (26 mg, 0.069 mmol), in DMF (0.23 mL) and THF (0.5 mL), DIPEA (0.014 mL, 0.083 mmol) was added. The reaction mixture was stirred at room temperature for 2 h. The mixture was diluted with MeOH and H2O, filtered and 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 bright yellow powder (8.0 mg, 48%). LCMS calc. for C41H50N11O5 (M+H)+: m/z=776.4. Found: 776.3.
