Procedure

2-Methylpropylamine (0.5 mL) was added to a suspension of 2,4-dichloro-3-nitroquinoline (1 g) and triethylamine (15 mL) at 40° C. over a period of 40 min. The solution was then heated at 70° C. for 1 h. The triethylamine and 2-methylpropylamine were removed by distillation and the residue was slurried for 1 h in aqueous 1N HCl. The solid product 2-chloro-N-(2-methylpropyl)-3-nitro-4-quinolinamine was collected by filtration, washed with water and recrystallized from petroleum ether.
