3-Chloroperoxybenzoic acid (1.83 g of approximately 75% pure material) was added to a stirred solution of methyl [1-(2-hydroxy-2-methylpropyl)-1H-imidazo[4,5-c]quinolin-2-yl]carbamate (1.0 g, 3.18 mmol) in dichloromethane (25 mL), and the reaction was stirred for 24 hours at room temperature. A precipitate formed and was collected by filtration, washed with a minimal amount of dichloromethane, and dried to provide 0.8 g of methyl [1-(2-hydroxy-2-methylpropyl)-5-oxido-1H-imidazo[4,5-c]quinolin-2-yl]carbamate as a solid.
