Reaction Steps

4-Fluoro-2-hydroxy-benzoic acid (10.8 g, 0.07 mol), sodium acetate (6.9 g, 0.084 mol), ethyl iodide (55 g, 0.35 mol) and dimethylformamide was stirred at ambient temperature for 48 h. The mixture was poured into water and extracted with n-hexane. The solution was filtered through a plug of silica gel and evaporated. The residue was almost pure product and was used directly in the next step. Yield 10.2 g, 80%.
