Water → N-(2-Methylpropyl)-3-nitro-1,5-naphthyridin-4-amine

Participants

Reaction Steps

Isobutylamine (15.6 mL, 157 mmol) was added dropwise to a 5° C. solution of 4-chloro-3-nitro[1,5]naphthyridine (15.0 g, 71.6 mmol) in dichloromethane (300 mL). The reaction was allowed to stir at room temperature for 4 hours, then was concentrated under reduced pressure to afford a residue that was treated with water (300 mL). The mixture was stirred for 30 minutes, then a solid was isolated by filtration, rinsed with water (100 mL), and dried in a vacuum oven at 50° C. overnight to afford 17.25 g of N-(2-methylpropyl)-3-nitro[1,5]naphthyridin-4-amine as a yellow solid.
