Versuchsvorschrift

A mixture of 4-(3-amino-2-methylphenyl)-7-(4-methylpiperazine-1-carbonyl)-9H-carbazole-1-carboxamide (Example 3-2, 100 mg, 0.204 mmol), 5-fluoropicolinic acid (43.1 mg, 0.306 mmol), and HOAT (41.6 mg, 0.306 mmol) in acetonitrile (2 mL) was treated with DIEA (0.053 mL, 0.306 mmol) and EDC (78 mg, 0.408 mmol) and the mixture was stirred at rt. After 18 h, the mixture was diluted with methanol and purified by preparative HPLC. The aqueous residue from concentration of the appropriate effluent fractions was made basic with NaHCO3 (aq) and extracted three times with EtOAc. The combined organic phases were dried and concentrated to provide 4-(3-(5-fluoropicolinamido)-2-methylphenyl)-7-(4-methylpiperazine-1-carbonyl)-9H-carbazole-1-carboxamide as a light gray powder (111.5 mg, 92%). 1H NMR (400 MHz, methanol-d4) δ 8.58 (d, J=3.1 Hz, 1H) 8.31 (dd, J=8.8, 4.8 Hz, 1H) 7.96-8.03 (m, 2H) 7.82 (td, J=8.6, 2.6 Hz, 1H) 7.68 (d, J=0.9 Hz, 1H) 7.45 (t, J=7.9 Hz, 1H) 7.23 (dd, J=7.5, 0.9 Hz, 1H) 7.09 (d, J=7.9 Hz, 1H) 7.03-7.08 (m, 1H) 6.95-7.00 (m, 1H) 3.78 (br. s., 2H) 3.49 (br. s., 2H) 2.52 (br. s., 2H) 2.40 (br. s., 2H) 2.31 (s, 3H) 2.04 (s, 3H).
