Vorschrift

7-Bromo-2-butyl-1-isobutyl-1H-imidazo[4,5-c]quinolin-4-amine and trans-2-phenylvinylboronic acid were coupled according to the general procedure described in Part J of Example 1. Recrystallization from toluene followed by chromatography on silica gel (8% methanol in CH2Cl2) afforded 2-butyl-1-isobutyl-7-[(E)-2-phenylethenyl]-1H-imidazo[4,5-c]quinolin-4-amine, m.p. 215–216° C.
