N-(4-Cyano-3-trifluoromethylphenyl)-3-(4fluorophenylsulfonyl)-2-hydroxy-2-methylpropanamide of high purity is produced by oxidation of N-(4-cyano-3trifluoromethylphenyl)-3-(4-fluorophenylthio)-2-hydroxy-2methylpropanamide, using urea-hydrogen peroxide complex (UHP), in a mixture of a C1_4-carboxylic acid and an organic solvent, as the oxidizing reagent. N-(4-Cyano-3-trifluoromethylphenyl)-3-(4fluorophenylsulfonyl)-2-hydroxy-2-methylpropanamide is a known antiandrogen.

The invention relates to an improved process for production of Bicalutamide useful in the treatment of prostate cancer by oxidizing N[4-Cyano-3-trifluoromethyl)phenyl]-3-[(4-fluorophenyl)thio]-2-hydroxy-2-methyl propanamide with Hydrogenperoxide in the presence of ethylacetate as solvent, methanesulfonic acid and sodiumtungstate as catalysts, washing the reaction mixture with sodiumthiosulphate solution or sodium metabisulphite solution, charcolising and evaporating the reaction mixture adding hydrocarbon solvent, cooling to room temperature and filtering.
Bicalutamide is an oral nonsteroidal, anti-androgen drug used for prostate cancer. It binds to the androgen receptor. During the bulk synthesis of bicalutamide, various impurities are formed. The present work details the development of simple processes for the preparation of impurities of bicalutamide, viz bical-sulfoxides (6), bical-deshydroxy (10), bical-desfluoro (10a), bical-2-fluoro (10b), and bical-3-fluoro
