Procedure

Ethyl iodide (0.14 mL) was added to a mixture of methyl 4-benzyloxy-2-hydroxybenzoate (0.30 g) and potassium carbonate (0.32 g) in N,N-dimethylformamide (2.9 mL) at room temperature with stirring. The mixture was stirred at that temperature for 1.6 hrs and at 50° C. for 1.4 hrs. Water was added, and the resulting mixture was extracted with ethyl acetate. The organic layer was washed with water, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure to afford the title compound (0.29 g).
