실험 절차

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-propanol (7.20 ML, 94.5 mmol). The solution was stirred for 4 hours, 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.
