Participants

Reaction Conditions

Reaction Steps

A mixture of 5-chloro-2-nitrobenzenamine (6.0 g, 34.9 mmol) and NBS (6.06 g, 34.0 mmol) in HOAc (240 mL) was heated at 110° C. for 1 h. The solution was cooled to RT and the reaction mixture was poured into an ice-water (800 mL). The resulting solid was filtered, washed with water (50 mL×3), and dry under vacuum to afford 4.0 g (44%) of 4-bromo-5-chloro-2-nitrobenzenamine (246) as yellow solid: MS (ESI) m/z=250.9 (M−1).
