Reaction Conditions

Reaction Steps

Potassium carbonate (19.9 g, 144 mmol) was added to a mixture of 4-chloro-3-nitroquinoline (30 g, 144 mmol) and dichloromethane (150 mL). The reaction mixture was sparged with nitrogen. Triethylamine (21.8 g, 216 mmol) was added dropwise. The reaction mixture was cooled to 0° C. then a solution of 3,3-diethoxypropylamine (25.4 g, 173 mmol) in dichloromethane (50 mL) was added dropwise over a period of 15 minutes. The reaction mixture was stirred at room temperature for 3 hours. Dichloromethane and water (200 mL) were added. The layers were separated. The organic layer was washed with brine (×2). The combined aqueous layers were extracted with dichloromethane. The combined organic layers were dried over magnesium sulfate, filtered, and then concentrated under reduced pressure to provide 45 g of N-(3,3-diethoxypropyl)-3-nitroquinolin-4-amine.
