A concise and efficient aminobromination reaction for β-nitrostyrenederivatives by treatment with N,N-dibromourethane was developed. For the β-nitrostyrenederivatives, the aminobromination successfully proceeded at room temperature in CH3CN without catalysis or protection by an inert gas and gave products in excellent yields (80–97 %). For the β-methyl analogs, the reaction proceeded smoothly with
