(11S)-11-{[(4-Fluorobenzyl)oxy]methyl}-10,11-dihydro-8H-[1,4]oxazino[4′,3′:1,2]imidazo[4,5-c]quinoline (700 mg, 1.93 mmol) was dissolved in 25 mL of CHCl3 and treated with MCPBA (570 mg, 77% max). The reaction was allowed to stir overnight and then 10 mL of aqueous 2% Na2CO3 solution was added and the layers were separated. The aqueous portion was extracted with CHCl3 (3×20 mL). The combined organic layers were washed with brine, dried over Na2SO4, filtered, and concentrated under reduced pressure to afford (11S)-11-{[(4-fluorobenzyl)oxy]methyl}-10,11-dihydro-8H-[1,4]oxazino[4′,3′:1,2]imidazo[4,5-c]quinoline 5-oxide (732 mg) as an orange foam.
