Reaction Steps

To a solution of 7-bromo-4-chloro-3-nitroquinoline (10.00 g, 34.78 mmol) in dichloromethane (140 mL) was added triethylamine (10.2 mL, 73.1 mmol). The solution was cooled to 0° C., and 3-amino-1-butanol (2.80 mL, 36.5 mmol) was added. The solution was stirred overnight at ambient temperature and then filtered to collect a precipitate. The precipitate was washed with dichloromethane and water. The filtrate was washed with saturated aqueous sodium bicarbonate and then added to the precipitate. The mixture was concentrated under reduced pressure. Methanol and toluene were added several times and removed under reduced pressure. The resulting solid was dried under high vacuum to provide 11.34 g of 3-[(7-bromo-3-nitroquinolin-4-yl)amino]propan-1-ol as a yellow solid.
