Reaction Steps

To a solution of 2-[3-(4-chloro-phenyl)-5-methyl-pyrazol-1-yl]-4-[1-(5-fluoro-pyridin-2-yl)-meth-(Z)-ylidene]-cyclopentane-1,3-dione (17 mg, 0.04 mmol) in methanol (0.4 ml) was added 5% palladium on activated charcoal (2 mg) and the reaction stirred for 6 hours under 1.5 bar of hydrogen. The solution was then filtered through a pad of Celite, washed with methanol (10 ml) and concentrated in vacuo to give a white solid, which was purified by column chromatography using DCM:EtOAc:AcOH (9:1:0.01%) to (3:7:0.01%) to give 2-[3-(4-chloro-phenyl)-5-methyl-pyrazol-1-yl]-4-(5-fluoro-pyridin-2-ylmethyl)-cyclopentane-1,3-dione (15.7 mg).
