Procedure
To a solution of 2.20 g of 2-(3-hydroxybenzyl)-tetrahydro-2-furancarboxylate in 50 ml of methanol was added 0.5 ml of sulfuric acid, and the mixture was heated under reflux for 18 hours. The solvent was evaporated, and the residue was dissolved in 200 ml of ethyl acetate. The organic layer washed twice with 50 ml of water, and dried over anhydrous magnesium sulfate. The solvent was evaporated, and the residue was purified by silica gel column chromatography, to give 2.20 g of the title compound from the 7:3 hexane-ethyl acetate fraction.
