Reaction Steps

To a solution of 2-(4-fluoro-2,6-dimethylphenyl)-cyclopentane-1,3-dione (2.9 g, 13.3 mmol) in tetrahydrofuran (290 ml) is added anhydrous potassium carbonate (22 g, 159 mmol) and iodomethane (22.6 g, 159 mmol. The resulting mixture is stirred at 25-30° C. for 16 hours. The organic layer is evaporated, reaction mixture is quenched with water (150 ml) and extracted with ethylacetate (3×100 ml). The combined organic extracts are combined, washed with water and brine, dried over anhydrous sodium sulphate, filtered and the filtrate is concentrated in vacuo. The residue is purified by column chromatography on silica gel to give 2-(4-fluoro-2,6-dimethylphenyl)-3-methoxy-cyclopent-2-enone (2 g).
