Procedure

A mixture of 3-{[(benzyloxy)carbonyl]amino}-7-morpholin-4-ylquinoline-2-carboxylic acid (0.014 g, 0.034 mmol), tert-butyl [(3S,5R)-1-(3-aminopyridin-4-yl)-5-methylpiperidin-3-yl]carbamate (0.013 g, 0.041 mmol) and HATU (0.033 g, 0.086 mmol) in DMF (0.14 mL) and DIPEA (0.018 mL, 0.10 mmol) was stirred at room temperature for 2 h. The mixture was diluted with 5 mL of EtOAc and 3 mL of 1 M NaOH. The layers were separated and the aqueous layer was extracted with EtOAc. The organic layers were combined and concentrated under reduced pressure. The residue was purified by flash chromatography on 20 g silica gel column, eluting with 0-30% MeOH in EtOAc, to yield an amide intermediate, benzyl (2-{[(4-{(3S,5R)-3-[(tert-butoxycarbonyl)amino]-5-methylpiperidin-1-yl}pyridin-3-yl)amino]carbonyl}-7-morpholin-4-ylquinolin-3-yl)carbamate. LCMS calc. for C38H46N7O6 [M+H]+: m/z=696.3. found: 696.5.
