A mixture of benzyl [2-[({4-[(3R,4R,5S)-3-amino-4-hydroxy-5-methylpiperidin-1-yl]pyridin-3-yl}amino)carbonyl]-7-(4-methyl-3-oxopiperazin-1-yl)quinolin-3-yl]carbamate (0.0070 g, 0.011 mmol) in 3.0 mL of MeOH was hydrogenated in the presence of 8 mg of 10% Pd on carbon under a balloon of hydrogen at room temperature for 1 h. The mixture was then 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 C26H33N8O3 [M+H]+: m/z=505.3. found: 505.3.
