反応手順
A solution of 16.9 g of 4-ethylphenyl 4-trimethylsilyloxybenzoate (prepared according to the instructions in EP-A-0 358 205, page 9, section C) in 15 ml of toluene and 10 ml of ethanol was boiled under reflux for one hour and then freed from volatile constituents by heating at 100° C. for 60 minutes. The 13.3 g of 4-ethylphenyl 4-hydroxybenzoate which remained were dissolved, together with 30 g of methacrylic anhydride and 1.2 g of toluenesulfonic acid, in 15 ml of toluene and the solution was heated at 100° C. for 1 hour. After cooling, the product was precipitated with hexane and recrystallized from ethanol.
