Reaction Steps

To a solution of 2-(4-bromo-2,6-dimethylphenyl)-4-[1-(tetrahydropyran-4-yl)-methylidene]-cyclopentane-1,3-dione (0.1 g, 0.26 mmol) in methanol (100 ml) is subjected to hydrogenation under H-Cube conditions using 10% platinum carbon under a 20 bar hydrogen atmosphere. The reaction mixture is then concentrated to give a crude product which is purified by flash chromatography (hexane/ethyl acetate) to afford 2-(4-bromo-2,6-dimethylphenyl)-4-(tetrahydropyran-4-ylmethyl)cyclopentane-1,3-dione (0.09 g).
