(S)-2-phenyl-1,3-dioxan-5-yl 9-fluoro-3-methyl-10-(4-methylpiperazin-1-yl)-7-oxo-3,7-dihydro-2H-[1,4]oxazino[2,3,4-ij]quinoline-6-carboxylate (0.50 g, 9.55 mmol), was dissolved in a mixture of dichloromethane/methanol (2:1.5, 87.5 ml) under argon. Palladium catalyst (10 wt % Pd/C) (180 mg) was added, the flask was evacuated and allowed to stir 1 atm of hydrogen gas at room temperature for 16 hours. The crude reaction mixture was passed through a glass microfiber on a sintered funnel. The volatiles were removed under reduced pressure yielding 370 mg (88%) of a yellow gum.
