To a mixture of (2,6-dinitro-4-trifluoromethyl-phenyl)-methyl-amine (5.0 g), acetic acid (11 mL), ethanol (100 ml), and ice (20 g), iron powder (6.4 g) was added under ice-cooling. The reaction mixture was stirred at 0° C. for 3.5 hours, and filtered through Celite®. The resulting filtrate was concentrated under reduced pressure, and diluted with 1N aqueous sodium hydroxide solution. The solution was extracted with ethyl acetate. The combined organic layer was dried over sodium sulfate, and concentrated under reduced pressure to give 3.1 g of N′-methyl-5-trifluoromethyl-benzene-1,2,3-triamine.
