Procedure

To a solution of 2-(4-fluoro-2,6-dimethylphenyl)-4-[1-(tetrahydropyran-4-yl)-methylidene]-cyclopentane-1,3-dione (0.14 g, 0.44 mmol) in methanol (3 ml) is added 10% palladium on carbon (1.5 mg), followed by stirring under a 1 bar hydrogen atmosphere for 8 hours. The reaction mixture is then filtered through diatomaceous earth and concentrated to give a crude product which is purified by flash chromatography (hexane/ethyl acetate) to afford 2-(4-fluoro-2,6-dimethylphenyl)-4-[tetrahydropyran-4-ylmethyl)-cyclopentane-1,3-dione (0.13 g).
