Method for producing high purity N- (4-cyano-3-trifluoromethylphenyl) -3- (4-fluorophenylsulfonyl) -2-hydroxy-2-methylpropanamide |
| abstract |
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. |
