Reaction Steps
Potassium carbonate (1.244 g) was added to a solution of commercially available 2,6-dihydroxynaphthalene (961 mg) in N,N-dimethylformamide (100 ml), and the admixture was stirred at room temperature for 30 minutes. Dimethyl sulfate (1.14 ml) was slowly added dropwise to the mixture and the resulting mixture was further stirred at room temperature overnight. The reaction mixture thus prepared was neutralized with a 2N HCl solution and then partitioned between water and ethyl acetate, and the ethyl acetate layer was dried with anhydrous magnesium sulfate. After removing the solvent by distillation under reduced pressure, the resulting residue was purified by column chromatography on silica gel (eluting with chloroform/ethyl acetate) to obtain 307 mg of the title compound (yield: 29%).
