Abstract

Preparation process for 2-alkoxy-5-alkylsulfonylbenzoic acids that respond to the following general formula ** (See formula) ** wherein A and B are low molecular weight (1 to 5 carbon atoms) alcohol or alkenyl radicals, which consists of starting from p-bromophenol, alcoholizing it in order to obtain the corresponding p-bromoalkoxybenzene that is treated with a cuprous mercaptide to transform it into p-alcoholylthioalkoxybenzene; this compound is then oxidized to p-alcohol sulfonylalkyl benzene; by nitration, 1-nitro-2-alkoxy-5-alkylsulfonylbenzene is obtained, which is then reduced to the corresponding amine derivative; by diazotization and reaction of Sandmeyer with cuprous cyanide, the desired 2-alkoxy-5-alkylsulfonylbenzonitrile is obtained and by hydrolysis, the desired 2-alkoxy-5-alcoholylsulfonyl-benzoic acid is reached.
