Reaction Steps

A mixture of 8-carbamoyl-5-(2-fluorophenyl)-9H-carbazole-2-carboxylic acid (Example 23-2, 30 mg, 0.086 mmol), EDC (23.11 mg, 0.121 mmol), HOBT (18.46 mg, 0.121 mmol), DIEA (30 μL, 0.172 mmol), and 1-methylpiperidin-4-amine (9.83 mg, 0.086 mmol) in THF and DMF (4:1, 2 mL) was stirred at rt overnight. The mixture was concentrated and purified by preparative HPLC. The isolated product was partitioned between DCM and NaHCO3 (aq). The organic phase was dried and concentrated to provide 4-(2-fluorophenyl)-N7-(1-methylpiperidin-4-yl)-9H-carbazole-1,7-dicarboxamide as a white solid (25 mg, 62%). 1H NMR (400 MHz, DMSO-d6) δ 11.75 (s, 1 H) 8.24 (br. s., 1 H) 8.20 (s, 1 H) 8.13 (d, J=7.69 Hz, 1 H) 8.05 (d, J=7.91 Hz, 1 H) 7.52-7.68 (m, 3 H) 7.33-7.48 (m, 3 H) 7.13 (d, J=7.69 Hz, 1 H) 7.05 (d, J=8.35 Hz, 1 H) 3.64-3.80 (m, 1 H) 2.69-2.79 (m, 2 H) 1.87-2.00 (m, 2 H) 1.70-1.80 (m, 2 H) 1.48-1.65 (m, 2 H). Mass spectrum m/z 445.2 (M+H)+.
