실험 절차

7-Benzyloxy-2-methyl-1-(2-methylpropyl)-1H-imidazo[4,5-c]quinoline (16.11 g, 46.6 mmol), 10% palladium on carbon (4.96 g), and ethanol (380 mL) were combined. The mixture was shaken overnight under 50 psi (3.4×105 Pa) of hydrogen and then filtered. The solids were washed with ethyl acetate, and the filtrate was concentrated. Diethyl ether was added to the residue and a green solid formed. The solid was recrystallized from acetonitrile to give 6.63 g of 2-methyl-1-(2-methylpropyl)-1H-imidazo[4,5-c]quinolin-7-ol as a beige solid.
