3-Chloroperoxybenzoic acid (9.15 g of 70% pure material, 37.1 mmol) was added to a suspension of 1-{[2-(chloromethyl)-1H-imidazo[4,5-c]quinolin-1-yl]methyl}cyclobutanol (8.00 g, 26.5 mmol) in chloroform (100 mL) under a nitrogen atmosphere, and the reaction was stirred at room temperature overnight. Additional chloroform (200 mL) was added, and the solution was washed sequentially with saturated aqueous sodium bicarbonate (2×80 mL) and brine (20 mL), dried over magnesium sulfate, filtered, and concentrated under reduced pressure to provide 1-{[2-(chloromethyl)-5-oxido-1H-imidazo[4,5-c]quinolin-1-yl]methyl}cyclobutanol as a yellow solid.
