Procedure

DCPD (available from Aldrich, 248 mL, 1.852 mol), allylacetate (available from Aldrich, 500 mL, 4.63 mol) and hydroquinone (0.7 g, 0.006 mol) were charged into a 2 L high pressure reactor and heated to 190° C. The mixture was stirred at 300 rpm for 5 hours. After the reaction was completed, the resultant was cooled and transferred to a distiller. Vacuum distillation was carried out 2 times at 56° C. using a vacuum pump at 1 torr to obtain the product (yield: 30%, exo/endo=57/43).
