Procedure

1-({[(2E)-4,4-dimethoxy-3-methylbut-2-en-1-yl]oxy}methyl)-4-methoxybenzene (1.52 g, 5.71 mmol) was dissolved in acetonitrile (16.0 ml), followed by addition of 1N hydrochloric acid (4.00 ml) and the reaction solution was stirred at room temperature for one hour. Subsequently, 2N hydrochloric acid (4.00 ml) to the reaction solution was added and it was further stirred for four hours. The reaction solution was poured into a saturated aqueous solution of sodium hydrogen carbonate, which was then extracted with diethyl ether. After the organic layer was washed with water and brine sequentially, it was dried over anhydrous magnesium sulfate. The drying agent was filtered off and the organic layer was concentrated under reduced pressure to obtain the title compound (1.52 g) as a colorless oil.
