Versuchsvorschrift

8-Bromo-2-ethyl-1-isobutyl-1H-imidazo[4,5-c]quinolin-4-amine and benzeneboronic acid were coupled according to the general procedure described in Part J of Example 1. Chromatography on silica gel (5%-7% methanol in CH2Cl2 gradient) afforded 2-ethyl-1-isobutyl-8-phenyl-1H-imidazo[4,5-c]quinolin-4-amine as a white solid, m.p. 233-235° C.
