Triethylamine → 2-Methyl-2-adamantyl methacrylate

Participants

Reaction Steps

83.1 g of 2-methyl-2-adamantanol and 101 g of triethylamine were charged, and 200 g of methyl isobutyl ketone was added thereto to prepare a solution. Then, 78.4 g of methacrylic acid chloride (1.5 mole times with respect to 2-methyl-2-adamantanol) was added dropwise thereto, followed by stirring at room temperature for 10 hours. After filtration, the organic layer was washed with a 5% by weight aqueous solution of sodium bicarbonate, followed by washing with water for 2 times. The organic layer was concentrated, and then subjected to distillation under reduced pressure to obtain 2-methyl-2-adamantyl methacrylate represented by the following formula in a 75% yield.
