실험 절차

A mixture of 7-bromo-4-chloro-3-nitro[1,5]naphthyridine (92.5 g, 321 mmol) and dichloromethane (1.5 L) was cooled to 10° C. 1-Amino-2-methylpropan-2-ol (63.01 g, 707 mmol) was added dropwise over a period of 30 minutes; during the addition, the reaction temperature did not rise above 13° C. The reaction mixture was allowed to warm to room temperature slowly and stirred overnight. The solvent was removed under reduced pressure, and the solid residue was mixed with deionized water (200 mL). The solid was isolated by filtration, washed with deionized water (2×200 mL), and dried in a vacuum oven overnight at 35° C. to provide 1-[(7-bromo-3-nitro[1,5]naphthyridin-4-yl)amino]-2-methylpropan-2-ol.
