Water → 2-(3-(Bromomethyl)-5-fluorophenyl)acetic acid

Participants

Reaction Steps

Benzoyl peroxide (0.05 g) was added to a mixture of 2-(3-fluoro-5-methylphenyl)acetic acid (0.518 g) and N-bromosuccinimide (0.6 g) in DCM (10 mL). The reaction was heated at reflux for 1 h. DCM (10 mL) and water (20 mL) were added and the organic phase separated. The organic layer was washed with brine (20 mL), dried over sodium sulphate, filtered and evaporated in vacuo. The residue was triturated with toluene and the resulting white solid removed by filtration. The mother liquors were evaporated in vacuo to give the subtitled compound as a white solid which was used in the next step without further purification. Yield 0.38 g.
