Versuchsvorschrift

A solution of 1-(2-aminoethyl)-2-ethoxymethyl-7-(pyridin-3-yl)-1H-imidazo[4,5-c]quinolin-4-amine (2.00 g, 5.50 mmol) in chloroform (40 mL) was treated with triethylamine (1.62 mL, 11.6 mmol) and methanesulfonyl chloride (0.47 mL, 6.05 mmol). The reaction was stirred for 1.5 hours, and additional methanesulfonyl chloride (2 equivalents) was added. The reaction was stirred for 30 minutes, and then deionized water (15 mL) was added. A precipitate formed and was isolated by filtration, triturated once with methanol and twice with chloroform and 1% aqueous sodium carbonate, isolated by filtration, and dried overnight in an oven to provide 0.65 g of N-{2-[4-amino-2-ethoxymethyl-7-(pyridin-3-yl)-1H-imidazo[4,5-c]quinolin-1-yl]ethyl}methanesulfonamide as a white solid, mp 233–235° C.
