A modification of the general method described in Part L of Example 2 was used to treat 1-(2-methylpropyl)-2-propyl-1H-imidazo[4,5-c]quinolin-7-ol with tert-butyl 3-iodopropylcarbamate. The reaction mixture was diluted with water; a precipitate formed. The precipitate was isolated by filtration, washed with water and then with diethyl ether until the filtrate was clear, and dried overnight in a vacuum oven at 60° C. to yield tert-butyl 3-{[1-(2-methylpropyl)-2-propyl-1H-imidazo[4,5-c]quinolin-7-yl]oxy}propylcarbamate as a tan powder.
