実験手順
To methyl 4-(6-fluoro-7-(methylamino)-4-oxo-2H-benzo[e][1,3]oxazin-3(4H)-yl)benzoate (0.05 g, 0.15 mmol) was dissolved in dioxan (2 ml) and to it was added sodium hydroxide (0.012 g, 0.3 mmol) in water (0.5 ml) and the mixture stirred for 4 hr at room temperature. The solvent was removed under vacuum and the residue acidified, extracted with ethyl acetate (2×10 ml), dried over anhydrous sodium sulfate and concentrated to provide 4-(6-fluoro-7-(methylamino)-4-oxo-2H-benzo[e][1,3]oxazin-3(4H)-yl)benzoic acid (0.2 g, 41%). RP-HPLC: 1.8 min; ES-MS (M+H)+=317.0.
