Bromine → n-(3-Bromoacetyl-4-chlorophenyl)methanesulfonamide

Participants

Reaction Steps

N-(3-acetyl-4-chlorophenyl)methanesulfonamide (300 mg) was dissolved in dioxane (5 mL), and bromine (77 μL) was added dropwise with ice-cooling. After stirring at room temperature for 1 hour, the solvent was distilled off under reduced pressure. The residue was washed with a water/ethanol mixture (1:1) and then dried under reduced pressure to yield N-(3-bromoacetyl-4-chlorophenyl)methanesulfonamide (312 mg) as a colorless crystal.
