The obtained 4,5-(dimethylmethylenedioxy)-3-(1-ethoxyethoxy)-6-heptenal was dissolved in 2 ml of pyridine under a nitrogen atmosphere, and 442 mg of hydroxylamine hydrochloride was added at 0° C. The mixture was stirred at room temperature for 4 hours, and the obtained reaction mixture was diluted with ether. The diluted reaction mixture was washed with a saturated sodium chloride aqueous solution, dried over anhydrous magnesium sulfate, and then concentrated under reduced pressure to afford 1.00 g of 4,5-(dimethylmethylenedioxy)-3-(1-ethoxyethoxy)-6-heptenal oxime.
