Mode opératoire

90.0 g of methacrylamide was dissolved in 1,350 g of tetrahydrofuran (THF), and 944 mL of a 1.12 mol/L lithium diisopropylamide (LiDA) solution was dropwise added thereto at 5° C., followed by stirring for 10 minutes. Subsequently, 900 g of THF having 231.1 g of 1-adamantanecarbonyl chloride dissolved therein was added thereto, followed by stirring at 5° C. for 18 hours. After completion of the reaction, THF and t-butylmethylether (TBME) were added thereto, followed by washing with a 1 wt % aqueous hydrochloric acid solution and pure water, and concentration under reduced pressure. n-hexane was added to the obtained solution, and crystallization was conducted at 5° C., followed by filtration. The obtained solid was dried under reduced pressure, thereby obtaining 194.4 g of 1-adamantanecarboxylic acid methacrylamide (compound (51)).
