Procedure

To a suspension of 7-bromo-4-chloro-3-nitroquinoline (25.0 g, 87.0 mmol) in DMF (70 mL) was added triethylamine (18.2 mL, 130 mmol). A solution of iso-butylamine (9.50 mL, 95.7 mmol) in DMF (20 mL) was added dropwise. The viscous reaction mixture was stirred overnight at ambient temperature. Water (200 mL) was added and the mixture was stirred for 1 hour. A solid was isolated by filtration, washed with water, and dried in a vacuum oven overnight to yield 26.1 g of 7-bromo-N-(2-methylpropyl)-3-nitroquinolin-4-amine as a yellow powder.
