Procedure
A mixture of benzyl [2-({[4-((3R,4R,5S)-3-[(tert-butoxycarbonyl)amino]-4-{[tert-butyl(dimethyl)silyl]oxy}-5-methylpiperidin-1-yl)pyridin-3-yl]amino}carbonyl)-7-morpholin-4-ylquinolin-3-yl]carbamate (0.0035 g, 0.0042 mmol) in 3 mL of MeOH was hydrogenated under a balloon of hydrogen, in the presence of 3 mg of 10% Pd on carbon, at room temperature for 1 h. The reaction mixture was diluted with 5 mL of MeOH then filtered. The filtrate was concentrated under reduced pressure. The resulting residue was treated with 2 mL of MeOH and 2 mL of 4 M HCl in dioxane at room temperature for 1 h. The volatile solvents were removed under reduced pressure. The residue was dissolved in 4 mL of MeOH and treated with 0.5 mL of NH4OH solution, then filtered. 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 C25H32N7O3 [M+H]+: m/z=478.3. found: 478.3.
