Reaction Conditions

Reaction Steps

To a solution of N-(3,5-difluorophenyl)-3,5-difluoro-2-nitroaniline (1 g, 3.49 mmol) in AcOH (10.5 mL) was added iron powder (585 mg, 10.48 mmol) and the reaction mixture was heated to 100° C. for 1 h. The reaction mixture was cooled to rt and water was added. The organic layer was extracted with EtOAc and was basified by using satd. sodium bicarbonate solution. The organic phase was dried over sodium sulfate and concentrated in vacuo to provide N1-(3,5-difluorophenyl)-3,5-difluoro-benzene-1,2-diamine. The crude product was carried without further purification.
