Versuchsvorschrift

To 30 ml of tetrahydrofuran were added 5 mmol of 1-methacryloyloxy-3,5-dihydroxyadamantane, 15 mmol of acetoaldehyde, and 1 mmol of p-toluenesulfonic acid, and the mixture was stirred at 30° C. for 6 hours. The reaction mixture was condensed under acidic conditions and crystallized by adding to diethyl ether dropwise to give the object compound 1-methacryloyloxy-3,5-di(1-hydroxyethoxy)adamantane (acetal compound) represented by the following formula:
