Reaction Steps

A mixture of 2,4-dichloro-3-nitroquinoline (100 g) and N,N-dimethylformamide (180 mL) was stirred, and triethylamine (42 g, 4 eq) was added dropwise, followed by dropwise addition of 2-methylpropylamine (21.5 g, 0.7 eq). The mixture was stirred at room temperature until the reaction was completed as determined by gas chromatography. Aqueous hydrochloric acid (250 mL, 4N) was added with stirring. The resulting mixture was stirred and cooled to about 0° C. to precipitate the product. The precipitate was filtered, washed with water, and dried at reduced pressure to afford the product 2-chloro-N-(2-methylpropyl)-3-nitro-4-quinolinamine in about 90% yield.
