Procedure

tert-Butyl (4S)-4-amino-5-[(methylsulfonyl)amino]pentylcarbamate (6.88 g, 23.3 mmol) was dissolved in 100 mL of dry CH2Cl2 and the solution was cooled to 0° C. under N2. Triethylamine (6.49 mL, 46.6 mmol) and 4-chloro-3-nitroquinoline (4.85 g, 23.3 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 triturated with 100 mL of hot H2O with stirring. The suspension was cooled and filtered to give 12.0 g of a pasty, yellow solid. The pasty solid was dissolved in methanol and CHCl3 and concentrated to give a yellow solid. The solid was then stirred in 100 mL of hot CHCl3, cooled and the solid was collected by filtration to give tert-butyl (4S)-5-[(methylsulfonyl)amino]-4-[(3-nitroquinolin-4-yl)amino]pentylcarbamate (8.00 g) as a yellow powder.
