2-{(3E)-4-[2-ethoxymethyl-1-(3-isopropoxypropyl)-1H-imidazo[4,5-c]quinolin-7-yl]but-3-enyl}-1H-isoindole-1,3(2H)-dione (1.9 g, 3.6 mmol) was dissolved in ethanol (50 mL) and added to a Parr flask containing 10% palladium on carbon (0.3 g) wetted with ethanol. The flask was degassed three times, charged with hydrogen (50 psi) and shaken for 16 hours. The catalyst was removed by filtration through CELITE filter agent. Concentration of the filtrate under reduced pressure provided 1.9 g of 2-{4-[2-ethoxymethyl-1-(3-isopropoxypropyl)-1H-imidazo[4,5-c]quinolin-7-yl]butyl}-1H-isoindole-1,3(2H)-dione as a pale yellow oil.
