Procedure

A reaction was conducted at a refluxing temperature for 3 hours using no magnesium sulfate but using a Dean-Stark dehydrating apparatus. Toluene was used as a solvent. The other operating conditions were the same as in Example 16, and a reaction, a post-treatment, etc. were conducted. 1.0 g of a crude product was obtained. However, the purity of 2-methyl-2-adamantyl methacrylate in the crude product was 15% and 2-methyleneadamantane was formed by 80%.
