Procedure

To a solution of methyl 5-chloro-2,4-dihydroxybenzoate (0.41 g, 2 mmol) in acetone were added 1-(chloromethyl)-4-methoxybenzene (0.32 g, 2 mmol) and K2CO3 (0.28 g, 2 mmol). The reaction mixture was heated with reflux for 3 days, than cooled to room temperature. The inorganic material was removed by filtration. The solvent was distilled in vacuo, and the residue was recrystallized from methanol to afford white solid (0.37 g, 60%).
