Stirring was continued under reflux for 32 hours. After cooling, the reaction mixture was filtered to separate calcium carbonate, the liquid was dried over magnesium sulfate, and then evaporated to dryness using a rotary evaporator to give 4-cyano-2,3,
2.6 g of 5,6-tetrafluorophenyl methacrylate (yield 63.9%, purity 95.4%) was obtained.
The analysis results for determining the structure of the obtained new substance were the same as in Example 2.
