Reaction Steps

A solution of 2-{[5-(trifluoromethyl)pyridin-2-yl]methylidene}cyclopentan-1-one (0.513 g, 2.13 mmol) in ethyl acetate (20 ml) was added palladium on carbon (10% wt, 50% wet, 0.226 g, 0.11 mmol) and the resulting mixture was stirred under a balloon of hydrogen gas for 2 hours. The reaction was filtered through diatomaceous earth (commercially sold under the trade mark “Celite”) and concentrated in vacuo. The crude product was purified by column chromatography (silica, 0-40% ethyl acetate/petrol) to afford the title compound.
