Under a nitrogen atmosphere, a solution of 1,2-diamino-2-methylpropane (52.20 mL, 503.3 mmol), triethylamine (131.8 mL, 958.8 mmol), and dichloromethane (1.0 L) was chilled in an ice water bath. 4-Chloro-3-nitroquinoline (100.0 g, 479.4 mmol) was added in portions over a period of 5 minutes. The reaction mixture was stirred at 0° C. for 2 hours and then allowed to slowly warm to ambient temperature. After 16 hours the reaction mixture was concentrated under reduced pressure. The residue was triturated with water (500 mL) for 1 hour. The resulting solid was isolated by filtration and dried overnight in a vacuum desiccator to provide 124.6 g of N1-(3-nitroquinolin-1-yl)-2-methylpropane-1,2-diamine as a yellow crystalline solid.
