A mixture of 2-methylsulphonyl-3-phenylsulphenylbenzoic acid and N,N-dimethylformamide (0.25 ml) in thionyl chloride was heated at reflux for 1.25 hours. The solution was evaporated to give 9.9 g of 2-methylsulphonyl-3-phenylsulphenylbenzoyl chloride as a pale yellow oil which was used directly in the next step without further purification.
