Versuchsvorschrift

To a solution of 27.9 g of tricyclo[6.2.2.02,7]dodeca-4,9-diene-3,6-diol in 165 mL of pyridine were portionwise added 30 mL of POCl3 at 0° C. The reaction was stirred for 3 days at rt before it was quenched by careful addition of ice under cooling. The resulting mixture was extracted with Hept (4×50 mL). The combined organic phases were washed with H2O, 15% HCl solution and again with H2O. The organic phase was dried over MgSO4 and concentrated in vacuo to obtain 10.6 g of the desired compound as yellow oil.
