Reaction Steps

To a aqueous solution of 1M NaOH (9.9 mL) heated at 50° C., was added slowly a solution of ethyl 5-(pyridin-2-yl)pent-4-ynoate (2 g, 9.90 mmol) in 3 mL of ethanol. The reaction mixture was stirred 1 h 30 at 50° C. and cooled to room temperature. An aqueous 1N HCl (9.9 mL, 9.90 mmol) was then added and the solvent was removed under pressure to afford 2.3 g of 5-(pyridin-2-yl)pent-4-ynoic acid (Yield: 99%) as a brown solid which can be used without further purification.
