反応手順
8-Bromo-2-ethyl-1-isobutyl-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 (5%–7% methanol in CH2Cl2 gradient) followed by recrystallization from isopropanol afforded 2-ethyl-1-isobutyl-8-(pyridin-3-yl)-1H-imidazo[4,5-c]quinolin-4-amine as white crystals, m.p. >250° C.
