Procedure
To a solution of ethyl (4E)-5-(2-pyridyl)-4-pentenoate (1.84 g) in ethanol (15 ml) was added 10% palladium on carbon (145 mg), and the mixture was stirred for 3 hours under an atmosphere of hydrogen (4 atm), and then filtered through a celite pad. Removal of the solvent in vacuo gave ethyl 5-(2-pyridyl)pentanoate (1.84 g).
