Reaction Conditions

Reaction Steps

To a solution of 5-(4-fluoro-2,6-dimethylphenyl)-4-hydroxy cyclopent-2-enone (3 g, 13.6 mmol) in acetone (36 ml) is added freshly prepared Jones reagent (24 ml) at 0° C. The resulting solution is stirred at 0° C. for 60 minutes. The reaction mixture is quenched with ice cold isopropyl alcohol (25 ml) and stirred for one hour. The organics evaporated under vacuo and extracted with ethyl acetate, dried over anhydrous sodium sulphate, filtered and the filtrate is concentrated in vacuo to give a residue which is purified by flash chromatography (hexane/ethyl acetate) to afford 2-(4-fluoro-2,6-dimethylphenyl)cyclopent-4-ene-1,3-dione (2.9 g).
