Versuchsvorschrift

Concentrated hydrochloric acid (˜15 mL) was added to a suspension of tert-butyl [4-(4-amino-7-bromo-2-propyl-1H-imidazo[4,5-c]quinolin-1-yl)butyl]carbamate (3.19 g, 6.7 mmol) in ethanol (6.4 mL), and the reaction was stirred for 30 minutes. The reaction was adjusted to pH 13 with the addition of 50% aqueous sodium hydroxide. A precipitate formed, was isolated by filtration, washed with 1% sodium carbonate, and dried overnight on the filter funnel to provide 1-(4-aminobutyl)-7-bromo-2-propyl-1H-imidazo[4,5-c]quinolin-4-amine, which contained some water.
