Versuchsvorschrift

19.91 g (0.497 mol) Sodium hydroxide was added to a solution of 71 g (0.226 mol) acetic acid 2-acetoxy-2-(5-ethyl-pyridin-2-yl)-ethyl ester in 355 mL water. Reaction mixture was stirred at 40° C. for 2 hr. After completion of reaction on TLC, reaction mixture was neutralized with con. HCl and precipitated solid was filtered off and dried to get 1-(5-ethyl-pyridin-2-yl)-ethan-1,2-diol. Yield of the product was 32.1 g (68%).
