Procedure

A mixture of 7-hydroxy-4-(2-methyl-3-(6-methyl-1-oxoisoindolin-2-yl)phenyl)-9H-carbazole-1-carboxamide (Example 40-2, 50 mg, 0.108 mmol) and potassium carbonate (30 mg, 0.217 mmol) in DMF (1.7 mL) was stirred at rt for 30 min, then was treated with racemic (4,4-dimethyl-1,3-dioxolan-2-yl)methyl 4-methylbenzenesulfonate (46.5 mg, 0.163 mmol). The resulting mixture was heated at 80° C. overnight. The mixture was cooled to rt, diluted with water and extracted with EtOAc. The organic phase was washed with brine, dried and concentrated. The residue was purified by column chromatography (eluting with a gradient from 50:50 to 80:20 EtOAc-hexane) to provide racemic 7-((2,2-dimethyl-1,3-dioxolan-4-yl)methoxy)-4-(2-methyl-3-(6-methyl-1-oxoisoindolin-2-yl)phenyl)-9H-carbazole-1-carboxamide as a light yellow solid (30 mg, 48%). Mass spectrum m/z 576.1 (M+H)+.
