Vorschrift

To 500 ml of toluene was dissolved 98 g of the 1,1-ethylenedioxy-4-hydroxy-4-(4-n-propylphenyl)cyclohexane mentioned above, 5 g of Amberlist 15E was added as catalyst thereto, and stirred under a reflux for 2 hours. After the reaction solution was cooled, the catalyst was filtered off. Organic layer was washed with water and dried over anhydrous magnesium sulfate, and the solvent was distilled off under a reduced pressure to obtain 90 g of 1,1-ethylenedioxy-4-(4-n-propylphenyl)-4-cyclohexene.
