Versuchsvorschrift

To a solution of 5-(11-fluoro-6H-pyrido[2′,3′:5,6][1,3]oxazino[3,4-a]indol-2-yl)-2-(2-methoxypyridin-4-yl)-N-methyl-6-(N-methylmethylsulfonamido)benzofuran-3-carboxamide (30 mg, 0.05 mmol) in HOAc (1 mL) was added HBr—HOAc (1 mL) at 0° C. Then the mixture was stirred at 80° C. for 2 hours. The solvent was removed by vacuum and NaHCO3 (a.q.) was added. The mixture was extracted with DCM, and the organic phase was dried over Na2SO4. After concentrated in vacuo, the residue was purified by prep-HPLC to give the product of 5-(11-fluoro-6H-pyrido[2′,3′:5,6][1,3]oxazino[3,4-a]indol-2-yl)-N-methyl-6-(N-methylmethylsulfonamido)-2-(2-oxo-1,2-dihydropyridin-4-yl)benzofuran-3-carboxamide (15 mg, yield: 52%). 1H-NMR (DMSO-d6, 400 MHz) δ 8.73˜8.75 (m, 1H), 8.11 (s, 1H), 7.85 (s, 1H), 7.73 (q, J=8.8 Hz, 1H), 7.59˜7.62 (m, 2H), 7.51˜7.61 (m, 2H), 7.25˜7.27 (m, 1H), 7.11 (s, 1H), 6.88˜6.96 (m, 1H), 6.65 (d, J=2.8 Hz, 1H), 6.27 (s, 2H), 3.31 (s, 3H), 2.97 (s, 3H), 2.85 (d, J=4.0 Hz, 3H).
