Procedure

4-Morpholinecarbonyl chloride (0.15 ml, 1.3 mmol) was added to a stirring solution of 1-(4-aminobutyl)-1H-imidazo[4,5-c]quinolin-4-amine (0.3 g, 1.2 mmol) and pyridine (70 ml). The reaction was maintained at room temperature overnight. The solvent was removed in vacuo and the residue was purified by flash column chromatography (silica gel, 9:1 dichloromethane\methanol). The fractions containing product were combined, washed with saturated aqueous sodium bicarbonate, dried (MgSO4), filtered, and concentrated to provide 0.86 g of N4-[4-(4-amino-1H-imidazo[4,5-c]quinolin-1-yl)butyl]4-morpholinecarboxamide as a tan powder, m.p. 177.0-179.5° C.
