22.2 g of p-methoxyallylbenzene was dissolved in 200 ml of chloroform and to the mixture was added dropwise, while maintaining the temperature at 0° -5° C, 31.3 g of m-chloroperbenzoic acid dissolved in 1l of chloroform. The resulting mixture was allowed to stand at the same temperature for 40 hours. After the separated m-chlorobenzoic acid was filtered off, the filtrate was washed with 5% sodium hydroxide solution, then with water and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure to obtain the residue, which was distilled under reduced pressure, there was obtained 15.4 g (yield 62.6%) of p-methoxyallylbenzene oxide having a boiling point of 90° C/2 mmHg.
