Reaction Steps
tert-Butyl (4S)-4-amino-5-{[tert-butyl(dimethyl)silyl]oxy}pentylcarbamate (3.76 g, 11.3 mmol) was dissolved in 100 mL of dry CH2Cl2 and the solution was cooled to 0° C. under N2. Triethylamine (3.10 mL, 22.3 mmol) and 4-chloro-3-nitroquinoline (2.36 g, 11.3 mmol) were then added and the reaction was allowed to warm to ambient temperature and stirred for 2 days. The reaction mixture was then concentrated under reduced pressure to give a yellow solid. The solid was dissolved in 200 mL of CH2Cl2 and was washed successively with H2O and brine. The organic portion was dried over Na2SO4, filtered and concentrated under reduced pressure to give yellow solid. Chromatography (SiO2, 20-35% ethyl acetate/hexanes) gave tert-butyl (4S)-5-{[tert-butyl(dimethyl)silyl]oxy}-4-[(3-nitroquinolin-4-yl)amino]pentylcarbamate (5.65 g) as a yellow syrup.
