Procedure

To a stirred solution of methyl1-[{[4-(2- butynyloxy)phenyl]sulfonyl}(methyl)amino]cyclohexanecarboxylate (4.6 g, 12.1 mmol) in methanol:THF (4:1, 100 ml), 10 N sodium hydroxide (15 ml) was added at room temperature. The reaction was stirred for 16 h and evaporated to dryness in vacuo and the residue was dissolved in 100 mL water. The pH was adjusted to 1 with 5N hydrochloric acid solution and the mixture was extracted with chloroform, washed with water, dried and concentrated to give 1-[{[4-(2-butynyloxy)phenyl]sulfonyl}(methyl)amino] cyclohexanecarboxylic acid as a yellow solid. Yield: 4 g(88%); mp 124-6° C. Electrospray Mass Spec 364(M−H)−.
