Reaction Steps

A solution of 1-[4-amino-2-(chloromethyl)-1H-imidazo[4,5-c]quinolin-1-yl]-2-methylpropan-2-ol (1.00 g, 3.28 mmol) in DMF (3.0 mL) was added to a solution of N-hydroxyphthalimide (642 mg, 3.94 mmol) and triethylamine (0.915 mL, 6.56 mmol) in DMF (3.0 mL). The flask containing the solution of 1-[4-amino-2-(chloromethyl)-1H-imidazo[4,5-c]quinolin-1-yl]-2-methylpropan-2-ol was rinsed with DMF (3.0 mL), which was added to the reaction solution. The solution was stirred at room temperature for 3 hours and a solid formed. The solid was isolated by filtration, washed with dichloromethane, and dried. The off-white solid was dissolved in hot DMF (20 mL). Acetonitrile (50 mL) was added to the solution, which was then placed in a freezer. Crystals formed and were isolated by filtration, washed with acetonitrile, and dried to provide 288 mg of 2-{[4-amino-1-(2-hydroxy-2-methylpropyl)-1H-imidazo[4,5-c]quinolin-2-yl]methoxy}-1H-isoindole-1,3(2H)-dione as orange crystals, mp 270.0-272.0° C.
