Procedure

Under a nitrogen atmosphere, triethylamine (72 g, 710 mmol) was added to a solution of 4-chloro-3-nitroquinoline (98.9 g, 474 mmol) in N,N-dimethylformamide (DMF) (1 L). A solution of tert-butyl 3-amino-2-hydroxypropylcarbamate (108.19 g, 569 mmol) in dioxane (800 mL) was slowly added, and the reaction was stirred overnight at ambient temperature and then poured into water (3 L) with continuous stirring. A precipitate formed and was isolated by filtration, washed with water, and dried for three days in a vacuum oven at 65° C. to provide 167.54 g of tert-butyl 2-hydroxy-3-[(3-nitroquinolin-4-yl)amino]propylcarbamate as a bright yellow powder.
