A solution of 7-(3-aminopropoxy)-1-(2-methylpropyl)-2-propyl-1H-imidazo[4,5-c]quinolin-4-amine (0.500 g, 1.41 mmol) in chloroform (15 mL) was cooled to 0° C.; 4-fluorobenzenesulfonyl isocyanate (0.548 g, 2.72 mmol) was added in three portions over a period of 30 minutes. A white precipitate was present and was isolated by filtration, washed with chloroform, and dried overnight in a vacuum oven at 60° C. to provide 0.671 g of N-{[(3-{[4-amino-1-(2-methylpropyl)-2-propyl-1H-imidazo[4,5-c]quinolin-7-yl]oxy}propyl)amino]carbonyl}-4-fluorobenzenesulfonamide as a white powder, mp 194-198° C.
