The Uses of 2-Chloro-5-hydroxypyridine
Used as a reagent in chemical research.
Preparation
2-Chloro-5-acetoxypyridine (21.66 g, 126 mmol) was dissolved in 300 mL of methanol and K2CO3(8.70 g, 63 mmol) was added. The reaction was stirred at room temperature for approx. 2 h, then concentrated in vacuo. The residue was diluted with diethyl ether and water, and the aqueous layer was adjusted to neutral pH by the addition of 1N aqueous HCl. Following extraction with diethyl ether, the organics were combined, washed with a solution of saturated aqueous NaCl, dried with MgSO4, and concentrated in vacuo. The resulting yellow solid (15.58 g, 96%) was used without further purification.
