Compound diethyl 2-(1-(pyridin-4-yl)propan-2-yl)malonate (2.50 g, 9.43 mmol) was refluxed in conc. HCl (30 ml) for 16 h. The pH of the reaction mixture was adjusted to 6 by adding solid sodium bicarbonate and extracted with ethyl acetate. The combined ethyl acetate layer was washed with brine, dried over anhydrous sodium sulfate, filtered and concentrated in vacuum to afford 1.20 g (76.9%) of 2-((pyridin-4-yl)methyl)propanoic acid as an off-white solid.
