According to Scheme 3 Step 2: A suspension of iron (5.07 mmol, 283 mg), acetic acid (1.22 mmol, 70 μL) and of 2-chloro-1-(3-chlorophenoxy)-4-nitrobenzene (1.02 mmol, 288 mg) in water/EtOH (1:1, 8 mL) was stirred at 80° C. for 30 minutes. After evaporation of EtOH, the aqueous phase was basified with a saturated solution of NaHCO3 and was extracted with AcOEt. The organic phase was washed with brine, was dried over MgSO4, was filtered and was concentrated under reduced pressure to yield 3-chloro-4-(3-chlorophenoxy)aniline (1.02 mmol, 258 mg, 100%) as a solid. The product was used without further purification.
