Reaction Steps

To a mixture of 3-{[(benzyloxy)carbonyl]amino}-7-bromoquinoline-2-carboxylic acid (47 mg, 0.12 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 (40 mg, 0.11 mmol), and HATU (100 mg, 0.27 mmol), in DMF (0.4 mL), DIPEA (0.056 mL, 0.32 mmol) was added. The reaction mixture was stirred at room temperature for 2 h then concentrated under reduced pressure. After concentration, the residue was purified by flash chromatography on silica using a CombiFlash® apparatus (0-100% EtOAc in hexanes) to give the sub-title compound as a light yellow powder (109 mg). LCMS calc. for C36H39BrN9O5 (M+H)+: m/z=756.2. Found: 756.3.
