To a solution of 2-[2-(4-Chloro-phenyl)-5-methyl-thiazol-4-yl]-4-[1-(tetrahydro-pyran-4-yl)-meth-(E)-ylidene]-cyclopentane-1,3-dione (130 mg, 0.32 mmol) in ethanol (2 ml) was added 5% palladium on carbon (13 mg), and the reaction stirred under an atmosphere hydrogen at a pressure of 2 bar for 4 hours. The crude reaction mixture was filtered through a pad of Celite and purified by preparative mass-directed HPLC to give 2-[2-(4-Chloro-phenyl)-5-methyl-thiazol-4-yl]-4-(tetrahydro-pyran-4-ylmethyl)-cyclopentane-1,3-dione (30 mg).
