Versuchsvorschrift

A solution of crude 7-(aminomethyl)-4-(2-methyl-3-(1-oxoisoindolin-2-yl)phenyl)-9H-carbazole-1-carboxamide (Example 33-1, 25 mg, 0.054 mmol), glycolic acid (8.26 mg, 0.109 mmol), HOAT (13.30 mg, 0.098 mmol), and EDC (20.81 mg, 0.109 mmol) in acetonitrile-THF (2:1) (5 mL) was treated with DIEA (0.028 mL, 0.163 mmol) and stirred at rt overnight. The mixture was concentrated and purified by preparative HPLC. The appropriate effluent fractions were concentrated to afford an aqueous suspension, which was treated with NaHCO3 (aq). The precipitate was collected by filtration, washed with water and dried to provide 7-((2-hydroxyacetamido)methyl)-4-(2-methyl-3-(1-oxoisoindolin-2-yl)phenyl)-9H-carbazole-1-carboxamide (17 mg, 59%). 1H NMR (400 MHz, DMSO-d6) δ 11.49 (1H, s), 8.22-8.28 (1H, m), 8.17 (1H, br. s.), 7.97-8.05 (1H, m), 7.81 (1H, d, J=7.5 Hz), 7.69 (2H, d, J=3.7 Hz), 7.54-7.66 (3H, m), 7.42-7.54 (2H, m), 7.28-7.38 (1H, m), 7.03 (1H, d, J=7.9 Hz), 6.94-7.00 (1H, m), 6.86-6.94 (1H, m), 5.45 (1H, br.), 4.88-5.05 (2H, m), 4.33-4.48 (2H, m), 3.88 (2H, s), 1.83 (3H, s). Mass spectrum m/z 519.2 (M+H)+.
