The oxidation of 1-isobutyl-1H-imidazo[4,5-c]quinoline produced in Example 3 is carried out in toluene at 40–45° C. using peracetic acid as oxidant to produce 1-isobutyl-1H-imidazo[4,5-c]quinoline N-oxide. The product is isolated by filtration after addition of a sodium sulfate solution and ammonium hydroxide.
