1-(2-(2-Aminoethoxy)-2-methylpropyl)-2-(ethoxymethyl)-1H-imidazo[4,5-c]quinolin-4-amine (32 mg, 89.5 μmol) was combined with DCM (1.0 mL) to give a colorless solution. To this solution was added triethylamine (25.0 μL, 179 μmol) and acetyl chloride (7.00 μL , 98.5 μmol) and the reaction mixture was stirred 18 hours at room temperature. After concentrating the mixture in vacuo the residue was purified by flash chromatography (silica gel-NH2, 0% to 10% methanol in DCM) to give the title compound (19 mg, 53%) as white foam; LC-MS (UV peak area, ESI) 97%, 400.2348 (MH+).
