Vorschrift

Methanesulfonyl chloride (1.27 g, 11.1 mmol) was slowly added to a solution of 1-(2-aminoethyl)-2-butyl-1H-imidazo[4,5-c]quinolin-4-amine (3.0 g, 10.6 mmol) in pyridine (60 mL). The reaction was maintained at ambient temperature overnight and then it was concentrated to dryness. The residue was combined with warm dichloroethane and water and then filtered to provide an off white solid. The dichloroethane layer was concentrated to provide an off white solid. The two solids were combined and then recrystallized from N,N-dimethylformamide to provide 1.1 g of N-[2-(4-amino-2-butyl-1H-imidazo[4,5-c]quinolin-1-yl)ethyl]methanesulfonamide as a white solid, m.p. 210.0–211 .0° C. Analysis: Calculated for C17H23N5O2S: % C, 56.49; % H, 6.41; % N, 19.37. Found: % C, 56.45; % H, 6.49; % N, 19.50.
