Procedure

A solution of the compound of Example 46, 1-[2-(2-aminoethoxy)ethyl]-2-ethyl-1H-imidazo[4,5-c]quinolin-4-amine (800 mg, 2.67 mmol) in 30 mL of pyridine was chilled in an ice water bath. With vigorous stirring, the solution was treated with 4-morpholinecarbonyl chloride (0.310 mL, 2.67 mmol). After 1 h, the reaction was concentrated to yield an off white solid. Purification by column chromatography (SiO2, 95:5:0.5 CHCl3:MeOH:NH4OH) followed by trituration in ether gave 563 mg of N-{2-[2-(4-amino-2-ethyl-1H-imidazo[4,5-c]quinolin-1-yl)ethoxy]ethyl}morpholine-4-carboxamide as a white solid.
