Procedure

1-BOC-3-bromo-5-bromomethyl-7-nitro-2-phenyl-indole prepared in Step B (1.0 g, 2 mmol) was dissolved in DCM (10 mL). Et3N (560 uL, 4 mmol) was added, 2-oxo-piperazine (300 mg, 3 mmol) was added, and the mixture was stirred for 12 h at room temperature. After completion of the reaction, saturated aqueous NH4Cl solution was added, and the reaction mixture was extracted with DCM. After drying, the solvent was removed under reduced pressure. The residue was purified by column chromatography to give the title compound (825 mg, Yield 78%).
