The bright yellow, homogeneous solution was stirred at ambient temperature for 2 hours at which time the starting material was completely consumed. The volatiles were removed under reduced pressure and he resulting solid stirred in water (400 mL) made basic (pH 10) with solid sodium carbonate. A bright yellow solid was collected by filtration to afford N-(3-chloropropyl)-3-nitroquinolin-4-amine (21.63 g, 81.41 mmol) which was used without further purification.
