The mixture was stirred at 0° C. for 6 hours, poured into 6N hydrochloric acid with ice and extracted with diethyl ether. The extract was washed with a saturated sodium hydrogen carbonate aqueous solution and a saturated sodium chloride aqueous solution in sequence, dried with anhydrous ride aqueous solution in sequence, dried with anhydrous magnesium sulfate, and concentrated under reduced pressure to afford 17.88 g of 3,4-(dimethylmethylenedioxy)-2-hydroxy-5-hexen-1-yl p-toluenesulfonate having the following properties.
