Procedure
6-Benzyloxy-5-methoxybenzofuran-2-carboxylic acid ethyl ester (7.3 g), acetic acid (45 ml) and conc. HCl (24 ml) were stirred at 50° C. for 0.5 hour. Water was added and pH adjusted to 3 with NaOH. The mixture was extracted with ethyl acetate. Ethyl acetate was dried with Na2SO4 and evaporated to dryness. The product was recrystallized from toluene.
