Reaction Steps

To a solution of 4-acetoxy-6-fluoro-naphthalene-2-carboxylic acid methyl ester (1 g, 3.8 mmol) in methanol (20 mL) was added sodium methoxide (309 mg, 5.7 mmol). After being stirred at room temperature for 1 hour, the reaction mixture was acidified to pH 3 with 1N hydrochloric acid. The resulting precipitate was collected by filtration and dissolved in ethyl acetate. The organic solution was dried over sodium sulfate, and concentrated in vacuo to afford 900 mg of crude 6-fluoro-4-hydroxy-naphthalene-2-carboxylic acid methyl ester as a pale yellow solid, which was used in the next step without further purification.
