Reaction Conditions

Reaction Steps

To a solution of 7-bromo-4-chloro-3-nitro[1,5]naphthyridine (22.53 g, 78.10 g) in dichloromethane (260 mL) at room temperature was added triethylamine (14.2 mL, 102 mmol). The solution was cooled to 0° C., and 3-amino-1-propanol (6.57 mL, 85.9 mmol) was added. The solution was stirred for 20 minutes at room temperature and then was concentrated under reduced pressure to yield a yellow solid. Water (250 mL) was added to the solid and the mixture was sonicated for 10 minutes. The solid was isolated by filtration, washed with water, and dried at 70° C. under vacuum to afford 22.60 g of 3-[(7-bromo-3-nitro[1,5]naphthyridin-4-yl)amino]propan-1-ol as a yellow powder.
