Procedure

Concentrated ammonium hydroxide (35 mL) was added with stirring to a solution of N-[3-(2-butyl-5-oxido-1H-imidazo[4,5-c]quinolin-1-yl)propyl]-N′-phenylurea (2.25 g, 5.39 mmol) in dichloromethane (100 mL). Tosyl chloride (1.13 g, 5.93 mmol) was added in small portions over a period of 30 minutes. After 1 hour the layers were separated. The aqueous layer was extracted with dichloromethane (2×25 mL). The organics were combined and extracted with water (3×50 mL). The aqueous layers were combined and filtered to provide 1.64 g of an off white solid. This material was recrystallized sequentially from 1,2-dichloroethane, isopropyl alcohol and methanol to provide 960 mg of N-[3-(4-amino-2-butyl-1H-imidazo[4,5-c]quinolin-1-yl)propyl]-N′-phenylurea as light tan needles, m.p. 191–192° C. Analysis: Calculated for C24H28N6O: % C, 69.21; % H, 6.78; % N, 20.18; Found: % C, 68.94; % H, 6.77; % N, 19.90.
