실험 절차

(2S)-1-(Benzyloxy)-3-{[tert-butyl(dimethyl)silyl]oxy}propan-2-amine (1.55 g, 5.25 mmol) was dissolved in 60 mL of dry CH2Cl2. Triethylamine (1.46 mL, 10.5 mmol) and 4-chloro-3-nitroquinoline (1.09 g, 5.25 mmol) were then added and the reaction was stirred under N2 for 2 days. The reaction mixture was then concentrated and the resulting material was partitioned between 50 mL of CH2Cl2 and 50 mL of saturated NaHCO3 solution. The layers were separated and the organic portion was washed with H2O and brine. The organic portion was dried over Na2SO4, filtered and concentrated under reduced pressure. Chromatography (SiO2, 0-10% ethyl acetate/CH2Cl2) gave 1.81 g of N-[(1S)-2-(benzyloxy)-1-({[tert-butyl(dimethyl)silyl]oxy}methyl)ethyl]-3-nitroquinolin-4-amine as a yellow solid.
