Procedure

A solution of 4-(3-amino-2-methylphenyl)-7-(1,2-dihydroxyethyl)-9H-carbazole-1-carboxamide (Example 70-4, 28 mg, 0.075 mmol), 5-fluoropicolinic acid (15.8 mg, 0.112 mmol), HOAT (18.3 mg, 0.134 mmol), and EDC (28.6 mg, 0.149 mmol) in acetonitrile-THF (2:1, 3 mL) was treated with DIEA (0.039 mL, 0.224 mmol) and stirred at rt overnight. The mixture was concentrated and purified by preparative HPLC. The residue from concentration of the appropriate effluent fractions was partitioned between NaHCO3 (aq) and EtOAc, and the organic phase was washed with brine, dried and concentrated to provide 7-(1,2-dihydroxyethyl)-4-(3-(5-fluoropicolinamido)-2-methylphenyl)-9H-carbazole-1-carboxamide as an off-white solid (20 mg, 53%). 1H NMR (400 MHz, DMSO-d6) δ 11.47 (1H, s), 10.38 (1H, s), 8.74 (1H, d, J=2.6 Hz), 8.28 (1H, dd, J=8.8, 4.8 Hz), 8.10-8.23 (1H, m), 7.95-8.04 (2H, m), 7.87-7.93 (1H, m), 7.72 (1H, s), 7.46-7.52 (1H, m), 7.43 (1H, t, J=7.6 Hz), 7.18 (1H, d, J=6.6 Hz), 6.97 (1H, d, J=7.7 Hz), 6.82-6.92 (2H, m), 5.22 (1H, t, J=3.5 Hz), 4.66-4.72 (1H, m), 4.56-4.64 (1H, m), 3.44 (2H, t, J=6.1 Hz), 1.97 (3H, s). Mass spectrum m/z 521.3 (M+Na)+.
