Abstract
Preparation process for 2-alkoxy-5-alkylsulfonylbenzoic acids that respond to the following general formula ** (See formula) ** in this formula: A and B are low molecular weight alcohol or alkenyl radicals (from 1 to 5 carbon atoms), which consists of starting from o-cresol, nitrosating it to give 5-nitroso-o-eresol, reducing the nitrosated derivative to give 5-amino-o-cresol which is treated with an alcoholizing agent to obtain the corresponding 2-alkoxy-5-aminotoluene; This compound, diazotized and treated with an alcohol mercaptan, leads to 2-alkoxy-5-alcoholylthiotoluene, which, oxidized, of the desired 2-alkoxy-5-alcoholylsulfonyl-benzoic acid.
