Sodium Hydroxide → 4-Bromobenzene-1,2-diamine

Participants

Reaction Steps

A solution of 4-bromo-2-nitroaniline (1.0 eq) and SnCl2 (2.2 eq) in EtOH was heated at reflux for 3 hours. After this time, the solution was poured onto ice, brought to pH 10 with 2M NaOH and extracted with Et2O. The combined organic layers were dried over MgSO4 and concentrated. The resulting brown oil was purified by silica gel chromatography (0-50% EtOAc:hexanes) to provide a light yellow solid. LC/MS m/z 187.1 (MH+), Rt 1.33 minutes.
