実験手順

To a solution of methyl 5-(11-fluoro-6H-pyrido[2′,3′:5,6][1,3]oxazino[3,4-a]indol-2-yl)-2-(4-fluorophenyl)-6-(N-methylmethylsulfonamido)benzofuran-3-carboxylate (60 mg, 0.10 mmol) in dioxane/H2O (11 mL/5 mL) was added LiOH.H2O (12.3 mg, 0.30 mol), and the mixture was stirred at 100° C. for 2 hours. After concentrated, the resulting residue was dissolved in H2O, 1 N HCl was added until pH reached 3, and the mixture was extracted with EtOAc. The organic layer was washed with brine, dried over Na2SO4 and filtered. The solvent was removed by distillation to provide 5-(11-fluoro-6H-pyrido[2′,3′:5,6][1,3]oxazino[3,4-a]indol-2-yl)-2-(4-fluorophenyl)-6-(N-methylmethylsulfonamido)benzofuran-3-carboxylic acid (41 mg, yield: 70%). 1H-NMR (DMSO-d6, 400 MHz) δ 13.36 (s, 1H), 8.26 (s, 1H), 8.13˜8.16 (m, 2H), 8.09 (s, 1H), 7.71 (d, J=8.4 Hz, 1H), 7.61 (d, J=8.4 Hz, 1H), 7.52 (d, J=8.4 Hz, 1H), 7.42˜7.46 (m, 2H), 7.25˜7.27 (m, 1H), 7.09 (s, 1H), 6.92˜6.96 (m, 1H), 6.28 (s, 2H), 3.30 (s, 3H), 2.98 (d, 3H).
