실험 절차

1.00 Gram of 6-(4-fluorophenylthio)-4-hydroxy-5-methyl-2-hexanone was dissolved in 100 ml of toluene, and 0.02 g of p-toluene sulfonic acid was added thereto. The resulting mixture was refluxed for 1.5 hours with stirring. After having been cooled, the mixture was washed with a saturated aqueous sodium hydrogencarbonate solution and then saturated aqueous sodium chloride solution. Then the mixture was dried over anhydrous magnesium sulfate. Removing the solvent from the mixture under reduced pressure gave 1.08 g of 6-(4-fluorophenylthio)-5-methyl-3-hexen-2-one. (trans : cis =3.7 : 1) (purity: 83.5%). The yield was 96.8%.
