To 1-cyclopropylmethyl-6-ethoxy-2-(4-nitro-phenyl)-1H-indole (800 mg, 2.38 mmol) in DMF (8.6 mL) at room temperature was added a solution of N-iodosuccinimide (585 mg, 2.6 mmol) in DMF (5.6 mL) dropwise. The reaction mixture was stirred at room temperature for 2 h, diluted with H2O and extracted with EtOAc. The organic layer was washed with H2O, and then with sat. aq. NaHCO3 and then dried and concentrated. The residue was triturated with hexane to provide 1-cyclopropylmethyl-6-ethoxy-3-iodo-2-(4-nitro-phenyl)-1H-indole (1.061 g, 96%) as an orange solid.
