실험 절차

1-(2-(2-Aminoethoxy)-2-methylpropyl)-2-(ethoxymethyl)-1H-imidazo[4,5-c]quinolin-4-amine (50 mg, 140 μmol) and 3-(triphenylmethoxy)-propanal (CAN 67057-68-5; 44.3 mg, 140 μmol) were combined with ethanol (500 μL) to give a light yellow suspension. The mixture was stirred for 2 hours at room temperature. Afterwards sodium borohydride (5.82 mg, 154 μmol) was added and stirring at room temperature continued overnight. The mixture was stirred with water (2 mL) and ethyl acetate (5 mL), dried by passage through a ChemElut® cartridge and concentrated in vacuo. The crude material was purified by flash chromatography (silica gel-NH2, 0% to 100% ethyl acetate in heptane) followed by another flash chromatography (silica gel, 0 to 10% methanol in ethyl acetate) to give the title compound (10 mg, 11%) as yellowish gum; LC-MS (UV peak area, ESI) 89%, 658.5 (MH+).
