The synthesis of 2-(ethoxymethyl)-1-propyl-1H-imidazo[4,5-c]quinolin-8-ol is described in Parts A-I of Example 2. The general method described in Part L of Example 2 was followed. 2-(Ethoxymethyl)-1-propyl-1H-imidazo[4,5-c]quinolin-8-ol (4.43 g, 15.5 mmol) was treated with tert-butyl 6-iodohexylcarbamate (prepared as described in Part F of Example 45, 6.1 g, 18.6 mmol). After the work up, the crude product was not purified to yield 9.9 g of tert-butyl 6-{[2-(ethoxymethyl)-1-propyl-1H-imidazo[4,5-c]quinolin-8-yl]oxy}hexylcarbamate as a tan waxy solid that contained DMF and dichloromethane.
