22.2 g of o-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 thus obtained mixture was allowed to stand for 55 hours at the same temperature. After 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 obtained the residue, which was distilled under reduced pressure, there was obtained 26.8 g (yield 54.5%) of o-methoxyallylbenzene oxide having a boiling point of 88.5° - 89.5° C/1 mmHg.
