3-Methylacetophenone → 1-(3-(Bromomethyl)phenyl)ethan-1-one

Participants

Reaction Steps

3′-Methylacetophenone (5.00 g; 37.3 mmol), N-bromosuccinimide (6.63 g; 37.3 mmol), and benzoyl peroxide (100 mg) were added to carbon tetrachloride (70 ml), and the mixture was refluxed for 1 hour. The mixture was left to cool to room temperature, and crystals that precipitated were removed by filtration. The filtrate was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography (n-hexane:ethyl acetate=20:1), to thereby yield 3.08 g of the target compound (yield: 38.8%).
