Procedure
8.38 g (0.02 mole) of ethyl 5-(3,5-dichlorophenylsulfonyl)-6-methyl-1,3-benzodioxole-2-carboxylate are covered with 30 ml of 2-n sodium hydroxide solution and the batch is heated for 1 hour in a boiling water bath, cooled and acidified, affording 5-(3,5-dichlorophenylsulfonyl)-6-methyl-1,3-benzodioxole-2-carboxylic acid. Melting point 210°-214° C. (crystallisation from ethyl acetate/toluene).
