Benzoyl peroxide (1.33 g) was added to a suspension of 2-chloro-3-methylbenzoic acid (25 g) and N-bromosuccinimide (28.7 g) in chlorobenzene (250 mL) and the resulting mixture was heated to 85° C. for 4 h. The mixture was diluted with ethyl acetate (100 mL) and washed with 10% aqueous brine (3×100 mL). The organic layer was dried over magnesium sulphate, filtered and evaporated. The beige solid was recrystallised from ethyl acetate (˜75 mL)/isohexane (˜250 mL) to give the subtitled compound as a white solid. Yield 25.3 g.
