Procedure

To a solution of 1.3 g of ethyl (E)-3-(5-ethyl-3-methoxy-4-methoxymethoxy-1-naphthyl)propenoate in ethanol (10 ml) was added 1 ml of concentrated hydrochloric acid and stirred at room temperature for 2 hours. Water was added to the reaction mixture and extracted with ethyl acetate. The organic layer was washed with water and brine and dried over anhydrous magnesium sulfate. After evaporation, hexane was added for crystallization to obtain 0.76 g of the titled compound as pale yellow crystals.
