1-(1,1-dimethylethyl) 7-methyl 2,3-dihydro-1H-indole-1,7-dicarboxylate (3.1 g, 11.2 mmol) and N-bromosuccinimide (2.0 g, 11.2 mmol) were dissolved in dry dichloromethane (100 mL) and stirred under a nitrogen atmosphere at room temperature for 16 hours. The reaction was partitioned with sodium hydroxide solution (2 M), separated and washed with more sodium hydroxide solution. The organic layer was dried over magnesium sulfate and concentrated in vacuo to give the title compound as a gummy red solid (3.55 g).
