Procedure
Equimolar portions (0.105 moles) of benzensulfonyl chloride, 3-hydroxy pyridine, (3-pyridinol) and sodium hydroxide were combined in 150 ml of water, heated to ca 50° C. for 1.5 hours, and allowed to stir at ambient temperature for 3 days. The product was extracted with methylene chloride, dried over sodium sulfate, and evaporated to yield an oil that was purified by distillation, bp 135° C. (0.02 torr) to yield 46% of the theoretical weight of 3-pyridinyl benzensulfonate.
