Reaction Steps

170 g of ethyl (Z)-3-(3-methoxy-4-methoxymethoxy-5-propyl-1-naphthyl)-2-methylpropenoate was dissolved in 850 ml of ethanol and a potassium hydroxide aqueous solution (potassium hydroxide 60 g/water 120 ml) was added, followed by refluxing for 1 hour. After cooling to 10° C., 2.5N hydrochloric acid was added to make it pH~5, followed by extraction with ethyl acetate. The organic layer was washed with brine, dried over anhydrous magnesium sulfate and concentrated in vacuo. The resultant crystals were filtered to obtain 151 g of the titled compound as yellow crystals.
