Reaction Conditions

Reaction Steps

Triethylamine (3.9 mL, 27.9 mmol, 1.2 eq) was added to a suspension of 4-chloro-3-nitro[1,5]naphthyridine (4.87 g, 23.3 mmol, 1.0 eq) in dichloromethane (100 mL). The resulting solution was cooled to 5° C. and 4,4-diethoxybutylamine (5.36 mL, 27.9 mmol, 1.2 eq) was added dropwise over a period of 5 minutes. The reaction mixture was allowed to stir at ambient temperature for 2 hours and then diluted with saturated aqueous sodium bicarbonate (100 mL). The phases were separated and the aqueous phase was extracted with dichloromethane (2×50 mL). The combined organics were dried over magnesium sulfate, filtered, and then concentrated under reduced pressure to provide 7.93 g of (4,4-diethoxybutyl)(3-nitro[1,5]naphthyridin-4-yl)-amine as a red solid.
