Procedure

A round bottom flask was charged with a magnetic stir bar, 4-chloro-3-nitroquinoline (109.70 g, 525.87 mmol) and dichloromethane (500 mL). To the solution was added triethylamine (79.82 g, 788.81 mmol) and 4-amino-1-butanol (46.87 g, 525.87 mmol) to give a homogeneous, dark yellow solution. The reaction was judged to be complete after heating at reflux for 30 minutes. The solution was cooled and then partitioned between chloroform and saturated aqueous ammonium chloride. The layers were separated and the aqueous layer was extracted with chloroform (1×). The organic layers were combined and then concentrated under reduced pressure to afford 4-[(3-nitroquinolin-4-yl)amino]butan-1-ol (104.67 g, 400.60 mmol) as a dark yellow solid. This material was used without further purification.
