Reaction Steps

In this embodiment, 0.1 mol of methacrylic acid and 8.6 grams (0.11 mol) of 3,4-dihydro-2H-pyran was dissolved in 150 ml of CH2Cl2. Small amounts of p-toluene sulfonic acid were then added to the resultant solution. The resultant solution was allowed to react at room temperature for four hours to form a reaction product. Then, the reaction product was dissolved in an excess amount of water to which diethyl ether was added to extract the reaction product. After drying the reaction product with a magnesiumsulfate solution, tetrahydropyranyl methacrylate was obtained through vacuum distillation.
