Diisopropylethylamine → Benzyl [2-{[(4-{(3S,5R)-3-[(tert-butoxycarbonyl)amino]-5-methylpiperidin-1-yl}pyridin-3-yl)amino]carbonyl}-7-(4-methylpiperazin-1-yl)quinolin-3-yl]carbamate

To a mixture of 3-{[(benzyloxy)carbonyl]amino}-7-(4-methylpiperazin-1-yl)quinoline-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), DIPEA (0.018 mL, 0.10 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 further extracted with EtOAc. The combined organic phases were concentrated under reduced pressure. The residue was purified by preparative HPLC (XBridge™ C18 column, eluting with a gradient of MeCN/water containing 0.1% NH4OH, at a flow rate of 30 mL/min.) to afford the sub-title compound. LCMS calc. for C39H49N8O5 [M+H]+: m/z=709.4. found: 709.5.
