Procedimiento

8-Bromo-1-isobutyl-1H-imidazo[4,5-c]quinolin-4-amine and thiophene-3-boronic acid were coupled according to the general procedure described in Part J of Example 1. Recrystallization from isopropanol followed by chromatography on silica gel (7% methanol in CH2Cl2) afforded 1-isobutyl-8-(thiophen-3-yl)-1H-imidazo[4,5-c]quinolin-4-amine as a white solid, m.p. 235–236° C.
