Participants

Reaction Steps

3 g of the 2,3,5,6-tetrafluoro-4-hydroxyphenylmaleimide obtained in Example 2 was dissolved in 20 ml of methylene chloride. Thereto was added 2.1 g of ethyl vinyl ether and 58 mg of pyridine salt of p-toluenesulfonic acid. The mixture was stirred at room temperature for 12 hours. 100 ml of ether was added. The mixture was washed with an aqueous sodium chloride solution. The organic layer was dried over magnesium sulfate. The resulting solution was subjected to vacuum distillation to remove the solvent to obtain 2.8 g of an intended compound (yield: 73%).
