Procedure

A solution of 1-acetyloxy-2,4-diethoxynaphthalene (2.74 g) in 100 ml of methanol and 10 ml of water was stirred with 2.5 g of potassium carbonate for 6 hours. The solvent was then removed under reduced pressure, and the residue partitioned between ethyl acetate and water. The ethyl acetate layer was dried over anhydrous sodium sulfate and evaporated to a solid, which was recrystallized from ethyl acetate/hexane to give 1-hydroxy-2,4-diethoxynaphthalene, m.p. 83°-84° C.
