Reaction Steps

A mixture of 4-chloro-1-(2-methylpropyl)-1H-imidazo[4,5-c]quinoline (66 g), methanol (266 mL) and ammonia (46.2 g) was placed in a steel bomb and heated at 150° C. for 8 h. The resulting mixture was filtered, and the solid was washed with water and dried to afford the product 1-(2-methylpropyl)-1H-imidazo[4,5-c]quinolin-4-amine in 70% yield.
