To the mixture is added ethyl acetate, and the organic layer is washed with water, dried over sodium sulfate, and the solvent is evaporated under reduced pressure. The residue is purified by silica gel column chromatography (eluent: gradient from 0% to 100% hexane/ethyl acetate) to give N-benzyl-6-nitroindole (1.4 g).
