To a solution of 2-hydroxy-5-(trifluoromethyl)benzoic acid (may be prepared as described in Description 117; 2 g, 9.70 mmol) in acetone (50 ml) was added 1-(bromomethyl)-4-fluorobenzene (4.04 g, 21.35 mmol), potassium carbonate (4.02 g, 29.1 mmol) and the reaction was heated to reflux overnight. The mixture was filtered to remove the solid potassium carbonate. The solid was washed with acetone (50 ml). The organics were combined and evaporated under reduced pressure on a buchi to yield the title compound. The crude yellow oil was used directly without further purification. 4.1 g.
