Procedure

To a solution of 2-((trimethylsilyl)ethynyl)pyridin-3-yl acetate (9.5 g, 41 mmol) in THF (200 mL) was added water (25 ml). The reaction was cooled to 0° C. and TBAF (1M, 45 ml, 45 mmol) was added. The mixture warmed to ambient temperature and stirred for 1 hour. Water (100 mL) was added and the volume was reduced by half. The product was extracted into ether (3×100 mL), washed with brine and dried over MgSO4. The solution was concentrated in vacuo to afford 2-ethynylpyridin-3-yl acetate (5.5 g, 34 mmol) as a light brown oil.
