Procedure

A solution of 7-(aminomethyl)-4-(2-methyl-3-(1-oxoisoindolin-2-yl)phenyl)-9H-carbazole-1-carboxamide (Example 33-1, 60 mg, 0.065 mmol) and TEA (23 μL, 0.163 mmol) in THF (1.3 mL) was treated with methanesulfonyl chloride (5.6 μL, 0.072 mmol) and the mixture was stirred at rt overnight. The mixture was concentrated and purified by preparative HPLC. The appropriate effluent fractions were concentrated and partitioned between EtOAc and NaHCO3 (aq). The organic phase was dried and concentrated, and the residue was purified further by column chromatography (eluting with a gradient from 40:60 hexane-EtOAc to EtOAc) to provide 4-(2-methyl-3-(1-oxoisoindolin-2-yl)phenyl)-7-(methylsulfonamidomethyl)-9H-carbazole-1-carboxamide as an off-white solid (7 mg, 18%). 1H NMR (400 MHz, DMSO-d6) δ 11.57 (1H, s), 8.19 (1H, br. s.), 8.02 (1H, d, J=7.7 Hz), 7.81 (1H, d, J=7.7 Hz), 7.73 (1H, s), 7.69 (2H, d, J=3.7 Hz), 7.61-7.65 (1H, m), 7.54-7.61 (2H, m), 7.51 (2H, t, J=7.7 Hz), 7.35 (1H, dd, J=7.5, 1.1 Hz), 7.00-7.08 (2H, m), 6.93-6.99 (1H, m), 4.88-5.05 (2H, m), 4.26 (2H, d, J=5.9 Hz), 2.87 (3H, s), 1.84 (3H, s). Mass spectrum m/z 539.2 (M+H)+.
