Procedure

3-Chloroperoxybenzoic acid (1.73 g of approximately 75% pure material) was added to a stirred solution of methyl [1-(2-methylpropyl)-1H-imidazo[4,5-c][1,5]naphthyridin-2-yl]carbamate (1.5 g, 5.01 mmol) in dichloromethane (40 mL), and the reaction was stirred for 76 hours at room temperature. A precipitate formed and was collected by filtration, washed with a minimal amount of dichloromethane, and dried to provide 0.9 g of methyl [1-(2-methylpropyl)-5-oxido-1H-imidazo[4,5-c][1,5]naphthyridin-2-yl]carbamate as a solid.
