Procedure

2-Amino-3-nitrobiphenyl d (0.613 g, 2.86 mmol) was purged under nitrogen for 30 minutes then HOAc (5 mL) was added followed by iron powder (0.4895 g, 8.76 mmol). The sample was heated at 60° C. for 30 minutes then HOAc (5 mL) was added. The sample was stirred at 60° C. for 1 hour then poured into ice. The sample was extracted with EtOAc (3×100 mL). The EtOAc extracts were washed with saturated NaHCO3 (3×100 mL. The EtOAc layer was dried over MgSO4, filtered, and concentrated to give 2,3-diaminobiphenyl e (0.439 g, 2.38 mmol, 83%).
