Versuchsvorschrift

A mixture of 73 g of 2-methyl-4-oxatricyclo[5.2.1.02,6]decan-3-yl acetate, 150 g of methacrylic acid, and 40 mg of 2,2′-methylenebis(6-t-butyl-p-cresol) was heated at 50° C. under atmospheric pressure for 30 minutes, after which under a reduced pressure of 0.20 kPa, the reaction mixture was heated for 18 hours for distilling off the acetic acid formed. The reaction mixture was purified by distillation, obtaining 72 g (yield 91%) of the target compound.
