Reaction Steps

A mixture of 4-chloro-2-nitrobenzenamine (2.0 g, 11.59 mmol) and 1-bromopyrrolidine-2,5-dione (2.3 g, 12.75 mmol) in MeCN (30 mL) was stirred at 70° C. for 14 h. The reaction mixture was poured into water (100 mL) and stirred at RT for 1 h. The precipitate was filtered and washed with water. The solid was dried under vacuum to afford 3-bromobenzene-1,2-diamine as a yellow solid (2.6 g, 86.7%).
