Reaction Steps

According to the general method of Example 14, 1-(4-aminobutyl)-1H-imidazo[4,5-c]quinolin-4-amine and 6-(2,2,2-trifluoroethoxy)pyridine-3-carbonyl chloride were combined to provide N3-[4-(4-amino-1H-imidazo[4,5-c]quinolin-1-yl)butyl]-6-(2,2,2-trifluoroethoxy)nicotinamide as a white crystalline solid, m.p. 192.0-194.0° C.
