実験手順

A mixture of 3-{[(benzyloxy)carbonyl]amino}-7-bromoquinoline-2-carboxylic acid (0.50 g, 1.2 mmol), tert-butyl ((3R,4R,5S)-1-(3-aminopyridin-4-yl)-4-{[tert-butyl(dimethyl)silyl]oxy}-5-methylpiperidin-3-yl)carbamate (0.54 g, 1.2 mmol), and HATU (1.2 g, 3.1 mmol) in DMF (4.9 mL) and DIPEA (0.65 mL, 3.7 mmol) was stirred at room temperature for 2 h, then quenched with 50 mL of EtOAc and 30 mL of 1 M NaOH. The resulting layers were separated and the aqueous phase was extracted with EtOAc. The combined organic extracts were concentrated under reduced pressure. The residue was purified by flash chromatography on a 40 g silica gel column, eluting with 0-100% EtOAc in hexanes, to give the sub-title compound (0.565 g, 55%). LCMS calc. for C40H52BrN6O6Si [M+H]+: m/z=919.3. found: 819.4.
