Procedure

4-Chloro-1-(2-methylpropyl)-1H-imidazo-[4,5-c]quinoline-2-methyl benzoate (5.0 g; 0.13 mol, Example 7) was added to 15% methanolic ammonia (50 mL). The mixture was heated in a Parr bomb for 7 hr at 175° C. The resulting solution was evaporated to reduce the volume. A sticky solid crystallized from the solution. The solid was filtered from the mixture and slurried in aqueous sodium bicarbonate solution. The resulting solid was filtered from the mixture, washed with water, and dried to yield 2.1 g (61.7%) of crude product which was recrystallized from ethanol several times to yield pure product m.p. 226-231° C. Analysis: Calculated: C, 66.6; H, 6.7; N, 20.7. Found: C, 66.4; H, 6.5; N, 20.4.
