Procedure
200 grams of dicyclopentadiene was put into a 500-ml flask equipped with a distillatory, and then was heated for reflux at 180° C. Then, about 100 grams of cyclopentadiene cracked at about 40° C. was dropped into 200 grams of t-butylacrylate with being cooled with ice bath. The resultant solution was stirred over a night. The resultant mixture was distilled under reduced pressure (66°-67° C./1 mmHg). As a result, there was obtained 296 grams of norbornenecarboxylic acid t-butylester. The yield was 98%.
