الإجراء التجريبي

DCPD (dicyclopentadiene, Aldrich, 67.32 mL, 0.5 mol), benzyl acrylate (Lancaster, 163 g, 1.0 mol) and hydroquinone (0.23 g, 2.1 mmol) were charged into a 2 L high-pressure autoclave, and the temperature was raised to 200° C. The resulting mixture was reacted for 5 hours with stirring at 300 rpm. After the reaction was completed, the reaction mixture was cooled and transferred to a distilling apparatus. The reaction mixture was distilled twice under a reduced pressure (1 torr) using a vacuum pump to yield the title compound at 190° C. (yield: 65%, exo/endo=56/44).
