実験手順
A solution of tert-butyl 6-{[4-amino-2-(ethoxymethyl)-1-(2-{[(isopropylamino)carbonyl]amino}-2-methylpropyl)-1H-imidazo[4,5-c]quinolin-7-yl]oxy}hexylcarbamate (4.20 g, 6.84 mmol) in 3 M HCl in ethanol (50 mL, 150 mmol) was heated at reflux for five minutes, then was allowed to cool to room temperature and was concentrated under reduced pressure. The resulting orange solid was dissolved water and the solution was washed with dichloromethane (2×). The aqueous layer was treated with ammonium hydroxide until a basic pH was reached, then was extracted with dichloromethane (3×). The combined organic layers were washed with brine, dried over sodium sulfate, filtered, and concentrated to yield 2.98 g of N-{2-[4-amino-7-[(6-aminohexyl)oxy]-2-(ethoxymethyl)-1H-imidazo[4,5-c]quinolin-1-yl]-1,1-dimethylethyl}-N′-isopropylurea as a dark orange solid.
