ethyl 3-piperidin-3-ylpropanoate

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A solution of ethyl 3-[pyrid-3-yl]prop-2-enoate (60 g, 0.34 mol) in ethanol (600 ml) was treated with 5% rhodium on alumina powder (17.2 g). The mixture was placed under a hydrogen atmosphere (55 psi) for five hours at 60° C. The reaction was stopped by removing the hydrogen and the reaciton mixture was filtered through a layer of CELITE™. The residue was washed with hot ethanol. The filtrate was concentrated and purified by flash chromatography to provide 39.6 grams (63%) of the desired title product. IR, NMR, and IR were consistent with the proposed title structure. for five hours at 60° C by removing the hydrogen the reaciton mixture was filtered through a layer of CELITE™ The residue was washed with hot ethanol The filtrate was concentrated purified by flash chromatography
