Procedure

Solid potassium carbonate (2.76 g, 20 mmol) was added to a stirred solution of 5-bromo-2-hydroxybenzoic acid (1 g, 4.61 mmol) in acetone (20 ml) at 20° C. The reaction mixture was stirred at 20° C. for 10 min, and then 1-(bromomethyl)-3-fluorobenzene (1.92 g, 10.14 mmol) was added dropwise. The reaction mixture was stirred at 71° C. for 18 h. After cooling to room temperature, the mixture was filtered. The filtrate was concentrated to give a colourless oil. The crude product was added to a silica gel column and was eluted with hexane/ethyl acetate (100:5 then 20:1) to yield the title compound as a white solid. 1.65 g.
