Procedure

To a solution of methyl o-toluate (15.0 g, 0.1 mol) in carbon tetrachloride (200 ml) were added N-bromosuccinimide (18.7 g, 0.1 mol) and benzoyl peroxide (catalytic amount) and the mixture was refluxed under heating for 2 hr. The reaction mixture was cooled to room temperature and the resulting precipitate was filtered off. The filtrate was concentrated under reduced pressure to give methyl α-bromo-o-toluate (yellow oil). The obtained oil was used in the next reaction without purification.
