Procedure
0.3 Gram of 4-hydroxy-6-(4-trifluoromethylphenylthio)-2-hexanone was dissolved in 30 ml of toluene, and 0.004 g of p-toluenesulfonic acid was added thereto. The resulting mixture was refluxed for 30 minutes with stirring, allowed to cool and then treated in the same manner as in Production example 34. Thus, 6-(4-trifluoromethylphenylthio)-3-hexen-2-one was obtained (purity: 98.5%).
