Procedure

To the intermediate tert-butyl {(3S,5R)-1-[3-({[3-amino-7-(1-methylpiperidin-4-yl)quinolin-2-yl]carbonyl}amino)pyridin-4-yl]-5-methylpiperidin-3-yl}carbamate, 1 mL of 4 M HCl in dioxane and 1 mL of MeOH were added. The mixture was stirred at room temperature for 1 h then concentrated under reduced pressure. The resulting residue was dissolved in 4.5 mL of MeOH and treated with 0.3 mL of NH4OH solution. The mixture was filtered and the filtrate 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 title compound. LCMS calc. for C27H36N7O [M+H]+: m/z=474.3. found: 474.4.
