Procedure

4-Chloro-1-(2-methylpropyl)-1H-imidazo[4,5-c]quinoline (10.0 g, 0.0385 moles, U.S. Pat. No. 4,689,338 Example 77) was added to hydrazine (30 ml). The mixture heated rapidly to reflux. The solid dissolved with a vigorous heat of reaction then a precipitate formed as the reaction mixture refluxed. The reaction mixture was diluted with water. The precipitate was isolated by filtration then suspended in water (100 mL). The solid was brought into solution by the addition of acetic acid. The solution was filtered to remove traces of undissolved solid. The filtrate was made basic by the addition of ammonium hydroxide. The resulting precipitate was isolated by filtration, washed with water then dried to provide 8.0 g of crude product as a white solid. A sample of this material was recrystallized from methanol to provide 4-hydrazino-1-(2-methylpropyl)-1H-imidazo[4,5-c]quinoline, m.p. 202-205° C. Analysis: Calculated for C14H17N5 : %C, 65.86; %H, 6.71; %N, 27.43; Found: %C, 65.20; %H, 6.6; %N, 27.5.
