Procedure

Ethyl 5-(2-pyridyl)valerate (3.6 g, 17.2 mmol) was dissolved in ethanol (12 ml), and 2 M aqueous sodium hydroxide solution (12.9 ml, 25.8 mmol) was added thereto. The reaction mixture was stirred at room temperature for 1.5 hrs. The solvent was evaporated, and the residue was combined with ethanol and filtered to remove the insolubles. The filtrate was concentrated to give the titled compound (2.5 g, 82%)
