Reaction Steps

To a solution of N-(5-(11-fluoro-6H-pyrido[2′,3′:5,6][1,3]oxazino[3,4-a]indol-2-yl)-2-(4-fluorophenyl)-3-(hydrazinecarbonyl)benzofuran-6-yl)-N-methylmethanesulfonamide (20 mg, 0.03 mmol) and Et3N (1 mL) in MeCN (5 mL) was added ethyl formimidate (6 mg, 0.05 mmol). Then the mixture was stirred at 110° C. for 2 hours. After the solvent was removed by vacuum, the resulting residue was purified using prep-HPLC to provide Compound 159 (10 mg, yield: 40%). 1H-NMR (CDCl3, 400 MHz) δ 9.01 (s, 1H), 8.35 (s, 1H), 8.10 (t, J=2.8 Hz, 2H), 7.89 (s, 1H), 7.48 (t, J=2.8 Hz, 2H), 7.15˜7.23 (m, 4H), 7.07 (s, 1H), 6.78 (t, J=2.8 Hz, 1H), 5.98 (s, 2H), 3.29 (s, 3H), 2.89 (s, 3H). MS (M+H)+: 626.
