Reaction Steps

2-Fluoro-2-methylpropan-1-amine hydrochloride (4.02 g, 31.4 mmol) was dissolved in 80 mL of dry CH2Cl2. Triethylamine (13.1 mL, 94.2 mmol) and 4-chloro-3-nitro[1,5]naphthyridine (6.56 g, 31.4 mmol) were then added and the reaction was stirred under N2 for 2 days. The reaction mixture was then concentrated under reduced pressure to give a dark-yellow solid. The solid was treated with 200 mL of H2O and the mixture was heated to reflux with rapid stirring. The mixture was cooled and the yellow solid was isolated by filtration. The material was washed with H2O and the dried under vacuum to give N-(2-fluoro-2-methylpropyl)-3-nitro[1,5]naphthyridin-4-amine (8.36 g) as a yellow powder.
