Versuchsvorschrift

180 g of 2-Ethyl-2-adamantanol, 303 g of triethylamine and 500 g of methylisobutyl ketone were mixed by stirring at 90° C. While stirring, 157 g of methacrylic acid chloride was added dropwise to the mixture. After completion of the dropwise addition, the mixture was further stirred for 72 hours. Then, extraction and distillation were conducted to obtain 2-ethyl-2-adamantyl methacrylate at the yield of 60%.
