Procedure

DCPD (Aldrich, 180 mL, 1.34 mol), butyl acrylate (Junsei, 500 mL, 3.49 mol), and hydroquinone (2.7 g, 0.025 mol) were put in a 2 L autoclave. After heating to 190° C., reaction was carried out for 5 hours while stirring the autoclave 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 80° C. to obtain the product (yield: 78%). The molar ratio (mol %) of exo/endo isomers of the product was 56.2:43.8.
