実験手順

tert-Butyl 4-[(4-amino-7-bromo-2-ethoxymethyl-1H-imidazo[4,5-c]quinolin-1-yl)methyl]piperidine-1-carboxylate (12.79 g, 24.67 mmol) and pyrdine-3-boronic acid 1,3-propanediol cyclic ester (4.42 g, 27.14 mmol) were coupled according to the method described in Examples 118–121. The work-up procedure described in Part F of Examples 125–135 was followed. The crude product was recrystallized twice from ethyl acetate to provide 10.89 g of tert-butyl 4-{[4-amino-2-ethoxymethyl-7-(pyridin-3-yl)-1H-imidazo[4,5-c]quinolin-1-yl]methyl}piperidine-1-carboxylate as an off-white solid, mp 197–198° C.
