Procedure

To a solution of 1-benzyl-N-(3,4-difluorobenzyl)-6-formyl-2-isopropyl-1H-indole-3-carboxamide (Compound 53, 18 mg, 0.040 mmol) in CH2Cl2 (1 ml) at 0° C. under argon was added ethylene diamine (2.5 mg, 0.042 mmol). The mixture was stirred at 0° C. for 30 minutes, and then added NBS (8 mg, 0.042 mmol). The reaction was stirred at 25° C. for 12 h, quenched with NaHCO3 (aqueous), diluted with EtOAc, washed with H2O, brine, dried over Na2SO4, concentrated in vacuo. The residue was purified by chromatography on silica gel (100% EtOAc) to yield the title compound as a light yellow solid.
