To a mixture of 4-iodo-2-nitro-phenyl amine (2.0 g), 60% sodium hydride (oil) (330 mg), and DMF (20 ml) was added dropwise iodomethane (470 μL) while ice-cooling. The reaction mixture was heated to room temperature, and then stirred for 2 hours. To the reaction mixture was added water, and the mixture was extracted with ethyl acetate. The organic layer was dried over sodium sulfate, and concentrated under reduced pressure. The residue was subjected to silica gel column chromatography to give (4-iodo-2-nitro-phenyl)-methyl-amine (2.0 g).
