実験手順

in stage c) the chlorine substituent is converted into a second methylsulfonyl group by reacting 2-methyl-4-chloro-5-methylsulfonylbenzoic acid with sodium methylthiolate and then oxidizing the thioether with an oxidizing agent, in particular sodium perborate, to give the corresponding intermediate 2-methyl-4,5-di(methylsulfonyl)benzoic acid,
