실험 절차
In 100 ml of ethanol, 7.0 g (40 mmol) of 1,3,3-trimethyl-2-methyleneindoline and 8.0 g (40 mmol) of 3-hydroxymethyl-1-nitroso-2-naphthol were dissolved and the solution was heated to reflux for 3 hours. After removal of the solvent, purification was conducted by column chromatography and recrystallization from hexane to obtain 3.0 g of 1,3,3-trimethyl-5'-hydroxymethylspiro [indoline-2,3'-[3H]-naphtho[2,1-b](1,4)oxazine] as a white solid. In 50 ml of methylene dichloride, 1.1 g (3 mmol) of the thus obtained spirooxazine compound was dissolved and 4 ml of triethylamine was added thereto, and then 0.5 g (5 mmol) of methacrylic acid chloride was added dropwise thereto at room temperature and the mixture was allowed to react. After removal of solvent, purification was conducted by column chromatography and recrystallization from hexane to obtain 1.0 g of 1,3,3-trimethyl-5'-methacryloxymethylspiro[indoline-2,3'-[3H]-naphtho[2,1 -b](1,4)oxazine] as a light yellow solid.
