実験手順

To a solution of methyl 4-ethylbenzoate (5.12 g) in carbon tetrachloride (50 ml) were added perbenzoic anhydride (0.20 g) and N-bromosuccinimide (6.07 g) in turn, and the mixture was heated and refluxed. After 30 minutes, the mixture was allowed to cool, and the precipitate was separated by filtration, and washed with carbon tetrachloride. The filtrate and the washings were combined, and concentrated under reduced pressure to give the title compound (8.28 g)
