Procedure

4-(4-But-2-ynyloxybenzenesulfonyl)-1-(3-pyridinylcarbonyl)-4-piperidine carboxylic acid was prepared following the procedure of Example 64 (step 5). Starting from Methyl 4-(4-but-2-ynyloxybenzenesulfonyl)-1-(3-pyridinylcarbonyl)-4-piperidinecarboxylate (430 mg, 0.94 mmol) in 8 ml of tetrahydrofuran:methanol (1:1), and 1N sodium hydroxide (1.89 ml, 1.89 mmol) to obtain 235 mg (57%) of the acid. HR—MS: m/z Calculated for C22H22N2O6S 443.1271; Found 443.1270.
