Reaction Steps

1-(4-Aminobutoxy)-2-butyl-1H-imidazo[4,5-c]quinolin-4-amine fumarate (1.30 g) was dissolved in dichloromethane (25 mL) and the solution washed with 3×15 ml portions of saturated sodium carbonate. The organic fraction was then washed with 15 ml saturated sodium chloride and dried over MgSO4. The solution was filtered, the solvent removed under reduced pressure and the product was dried under vacuum to give 0.79 g of 1-(4-aminobutoxy)-2-butyl-1H-imidazo[4,5-c]quinolin-4-amine as the free base.
