Versuchsvorschrift

To a suspension 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 (20 mg, 0.03 mmol) and K2CO3 (10 mg, 0.06 mmol) in DMF (1 mL) was added CH3I (5 mg, 0.03 mol) at 0° C. under N2, and then the mixture was stirred for 12 hours at room temperature. After being concentrated in vacuo, the resulting residue was suspended in H2O and extracted with DCM. The combined organic layer was washed with H2O and dried over Na2SO4. After concentration, 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-2-(1-methyl-2-oxo-1,2-dihydropyridin-4-yl)-6-(N-methylmethylsulfonamido)benzofuran-3-carboxamide (10 mg, yield: 49%). 1H-NMR (DMSO-d6, 400 MHz) δ 8.7˜28.74 (m, 1H), 8.10 (s, 1H), 7.84˜7.86 (m, 2H), 7.70˜7.72 (m, 1H), 7.59˜7.62 (m, 1H), 7.50˜7.53 (m, 1H), 7.24˜7.28 (m, 1H), 7.23 (s, 1H), 6.96˜7.09 (m, 2H), 6.67˜6.91 (m, 1H), 6.27 (s, 2H), 3.48 (s, 3H), 3.31 (s, 3H), 2.97 (s, 3H), 2.85 (d, J=4.4 Hz, 3H).
