General procedure for the synthesis of 2-fluoro-5-trifluoromethylaniline from 2-nitro-4-trifluoromethylfluorobenzene and iron powder: Referring to Example 1, 2-fluoro-5-trifluoromethylaniline was prepared as follows: 20 g of 3-nitro-4-fluorobenzotrifluoride was dissolved in 50 mL of methanol. Under stirring conditions, 16 g of iron powder was slowly added and concentrated hydrochloric acid was added dropwise. The reaction mixture was stirred at room temperature overnight. Upon completion of the reaction, an appropriate amount of sodium bicarbonate was added to neutralize the reaction solution. Subsequently, ether was added for extraction and the insoluble material was removed by filtration using diatomaceous earth. The ether phase was separated, dried over anhydrous sodium sulfate and concentrated under reduced pressure to give 14 g of the target product 2-fluoro-5-trifluoromethylaniline in 82% yield. | [References]
