To a solution of 2-isopropyl-6-nitro-1H-indole-3-carbaldehyde (Compound 121, 244 mg, 1.05 mmol) in DMF (10 ml) was added benzyl bromide (0.62 ml, 5.26 mmol) and K2CO3 (726 mg, 5.26 mmol). The reaction was stirred at room temperature for 16 h, diluted with EtOAc, washed with H2O and brine, dried over Na2SO4, and concentrated in vacuo. The residue was purified by chromatography on silica gel (0→50% EtOAc-hexanes) to yield the title compound.
