To a solution of 4-chloro-3-nitro[1,5]naphthyridine (18.0 g, 85.9 mmol) in dichloromethane (220 mL) at room temperature was added triethylamine (15.6 mL, 112 mmol) and 3-amino-1-butanol (7.20 mL, 94.5 mmol). The solution was stirred for 4 hours and then was concentrated under reduced pressure to yield an orange solid. The solid was slurried in water (250 mL) for 30 minutes, isolated by filtration, washed with water (3×30 mL), and dried at 70° C. in a vacuum oven to afford 20.9 g of 3-[(3-nitro[1,5]naphthyridin-4-yl)amino]propan-1-ol as a yellow solid.
