Next, 6 N hydrochloric acid (8 ml) was added to ethyl 2-acetyl-3-(4-pyridyl)propionate (1.20 g, 4.81 mmol), and the mixture was refluxed for 1.5 hours. The reaction mixture was concentrated under reduced pressure, 2-propanol (10 ml) was added to the concentrate, and the whole was concentrated under reduced pressure again. Ethyl acetate was added to the resulting solid, and the solid was filtered off to give 4-(4-pyridyl)-2-butanone (0.79 g, 89%) as a pale yellow solid.
