실험 절차

A suspension of 4-bromo-7-(4-methylpiperazine-1-carbonyl)-9H-carbazole-1-carboxamide (Example 1-1, 300 mg, 0.722 mmol), tetrakis-(triphenylphosphine)palladium (33.4 mg, 0.029 mmol), 2 M aqueous sodium carbonate (0.9 mL, 1.806 mmol), and 2-methyl-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)aniline (Intermediate 50-1, 253 mg, 1.084 mmol) in toluene-ethanol (4:1, 15 mL) was purged with nitrogen for 5 min and then heated at reflux for 7.5 h. The mixture was concentrated and the residue was partitioned between chloroform and water. The aqueous phase was extracted with chloroform and the combined organic phases were washed with brine, dried and concentrated. The residue was purified by column chromatography (eluting with DCM-2 M methanolic ammonia, gradient from 100:0 to 95:5) to provide 4-(3-amino-2-methylphenyl)-7-(4-methylpiperazine-1-carbonyl)-9H-carbazole-1-carboxamide as a white solid (207 mg, 65%). 1H NMR (400 MHz, DMSO-d6) δ 11.65 (s, 1H) 8.16 (br. s., 1H) 7.97 (d, J=7.91 Hz, 1H) 7.78 (s, 1H) 7.48 (br. s., 1H) 7.08 (t, J=7.80 Hz, 1H) 6.81-6.97 (m, 4H) 6.49-6.65 (m, 1H) 3.12-3.25 (m, 4H) 2.92-3.10 (m, 4H) 2.76 (s, 3H) 1.70 (s, 3H). Mass spectrum m/z 442.2 (M+H)+.
