10% hydrochloric acid (5 ml) was added to a methanol solution (5 ml) of 3-(3-methoxy-4-methoxymethoxy-5-methylphenyl)oxazolidin-2-one (0.48 g, 1.79 mmol) and the mixture was stirred at 50° C. for 10 minutes. Water was added to the reaction solution, which was extracted with ethyl acetate. The extracted material was dried over magnesium sulfate, and thereafter concentrated to dryness under reduced pressure to obtain 3-(4-hydroxy-3-methoxy-5-methylphenyl)oxazolidin-2-one (434 mg) as a light yellow powder.
