Procedure

DCPD (dicyclopentadiene, Aldrich, 256.5 ml, 1.9 mol), methylacrylate (Aldrich 405 ml, 4.5 mol), and hydroquinone (3.2 g, 0.03 mol) were put in a 2 L autoclave. After heating to 180° C., reaction was carried out for 5 hours while stirring at 300 rpm. After the reaction was completed, the reaction mixture was cooled down and transferred to a distillation unit. The reaction mixture was distilled at 1 torr using a vacuum pump at 50° C. to obtain the product (yield: 85%). The mole ratio (mol %) of exo-isomers to endo-isomers of the product was 41.1:58.9.
