Reaction Steps

Into a 500 mL, 3-necked round-bottom flask purged and maintained under an inert atmosphere of nitrogen, was placed a solution of 1,3-difluoro-2-(4-nitrophenoxy)benzene (20 g, 79.62 mmol, 1.00 equiv) in methanol (200 mL), Raney Nickel (2 g). A solution of hydrazine hydrate (12.67 g) in methanol (50 mL) was added dropwise with stirring in 15 min. The resulting solution was stirred for 12 h at 25° C., then filtrated and the filtrate was concentrated under vacuum. The residue was diluted with 200 mL of ethyl acetate, washed with water and brine, and dried over anhydrous sodium sulfate and concentrated under vacuum to give 16 g (91%) of 4-(2,6-difluorophenoxy)aniline as a black oil.
