Reaction Steps
8-Bromo-1-butyl-2-ethoxymethyl-1H-imidazo[4,5-c]quinolin-4-amine and pyridine-3-boronic acid were coupled according to the general procedure described in Part J of Example 1. Chromatography on silica gel (8%-10% methanol in CH2Cl2 gradient) followed by recrystallization from isopropanol (3×) and chromatography as above afforded 1-butyl-2-ethoxymethyl-8-(pyridin-3-yl)-1H-imidazo[4,5-c]quinolin-4-amine as a white solid, m.p. 220-222° C.
