Procedure
A suspension of tert-butyl 2-{[4-amino-1-[(2,2-dimethyl-1,3-dioxolan-4-yl)methyl]-2-(ethoxymethyl)-1H-imidazo[4,5-c]quinolin-7-yl]oxy}ethylcarbamate (prepared in Example 372, 1.5 g, 2.9 mmol) in ethanol (20 mL) and 4.3 M HCl in ethanol (2.70 mL, 17.5 mmol) was heated at reflux overnight. The reaction mixture was allowed to cool to room temperature and a white solid was collected by filtration, washed with ethanol, and dried under vacuum at 60° C. to yield 0.85 g of 7-(2-aminoethoxy)-1-[(2,2-dimethyl-1,3-dioxolan-4-yl)methyl]-2-(ethoxymethyl)-1H-imidazo[4,5-c]quinolin-4-amine dihydrochloride as a white solid, mp 221-223° C.
