Versuchsvorschrift

A glass flask equipped with a stirrer, two dropping funnels, a thermometer and a Dimroth condenser was charged with 16.6 g (0.1 mol) of 2-methyl-2-adamantanol, 23.1 g (0.15 mol) of methacrylic anhydride of 97% purity which is obtained by the process of example 1, 15.7 g (0.155 mol) of triethylamine, 0.6 g (0.005 mol) of dimethylaminopyridine, 70 ml of toluene and 0.005 g of HO-TEMPO, and the mixture was heated and stirred at 50° C. for 31 hours. It was confirmed that 2-methyl-2-adamantyl methacrylate was formed in the reaction mixture in a yield of about 40%. The resultant 2-methyl-2-adamantyl methacrylate was chromatographed on silica gel to obtain 9.1 g of 2-methyl-2-adamantyl methacrylate.
