Procedure
A vessel was charged with 83.1 g of 2-methyl-2-adamantanol and 101 g of triethylamine, and 200 g of methyl isobutyl ketone was added thereto to form a solution. To the solution was added dropwise 78.4 g of methacrylic acid chloride(1.5 times the molar amount of 2-methyl-2-adamantanol), followed by stirring for about 10 hours at room temperature. After filtration, the resulting organic layer was washed with an aqueous solution of 5 wt % sodium bicarbonate and then washed with water twice. The organic layer was concentrated and then distilled under reduced pressure to obtain 2-methyl-2-adamantyl methacrylate represented by the following formula.
