Procedure

To a solution of 2-chloro-4-hydroxybenzoic acid (3.45 g, 20 mmol) and sodium hydroxide (2.40 g, 60.0 mmol) in 30 ml of water is added, dropwise at 0°, methanesulfonyl chloride (2.57 ml, 3.80 g, 33.0 mmol). After addition is complete, the reaction mixture is stirred at RT for 30 min., after which it is poured into water, acidified with dil. HCl and extracted with ether. The combined organic extracts are washed with brine, dried and evaporated to give 2-chloro-4-methylsulfonyloxybenzoic acid.
