Versuchsvorschrift

A mixture of 3-{[(benzyloxy)carbonyl]amino}-7-morpholin-4-ylquinoline-2-carboxylic acid (0.005 g, 0.01 mmol), tert-butyl ((3R,4R,5S)-1-(3-aminopyridin-4-yl)-4-{[tert-butyl(dimethyl)silyl]oxy}-5-methylpiperidin-3-yl)carbamate (0.0064 g, 0.015 mmol), and HATU (0.012 g, 0.031 mmol) in DMF (0.2 mL) and DIPEA (0.0064 mL, 0.037 mmol) was stirred at room temperature for 2 h. The mixture was quenched with 5 mL of EtOAc and 3 mL of 1 M NaOH. The resulting layers were separated and the aqueous layer was extracted with EtOAc. The combined organic extracts were concentrated under reduced pressure, then purified by preparative HPLC (XBridge™ C18 column, eluting with a gradient of MeCN/water containing 0.05% TFA, at a flow rate of 30 mL/min.) to afford the sub-title compound (0.0032 g, 30%). LCMS calc. for C44H60N7O7Si [M+H]+: m/z=826.4. found: 826.4.
