Versuchsvorschrift

A suspension of 1-(4-aminobutyl)-7-bromo-2-propyl-1H-imidazo[4,5-c]quinolin-4-amine (2.00 g, 5.3 mmol) in chloroform (20 mL) was cooled to 0° C., and a solution of isopropyl isocyanate (5.3 mmol) in chloroform (3 mL/g) was added slowly over a period of eight minutes. After one hour, additional isopropyl isocyanate (0.53 mmol) in chloroform was added. Additional isopropyl isocyanate (2.15 mmol) was added again after an additional 2.5 hours. A precipitate was present and was isolated by filtration, washed with cold chloroform, and dried overnight on the filter funnel to provide 1.99 g of N-{4-[4-amino-7-bromo-2-propyl-1H-imidazo[4,5-c]quinolin-1-yl]butyl}-N′-(1-methylethyl)urea as a white solid.
