Procedure

Potassium permanganate (33.66 g) was added in portions to a stirred heated suspension of 2,4-dichloro-3-(methylsulphonyl)toluene (16.88 g) in water at 95°-100° C. The mixture was stirred and heated at reflux for one and a half hours. The hot suspension was filtered and the filtrate was cooled to 0° C. and acidified. It was filtered to give 2,4-dichloro-3-(methylsulphonyl)benzoic acid (5.35 g) as an orange solid, m.p. 157.5°-158.5° C.
