Reaction Steps

4-(4-But-2-ynyloxybenzenesulfonyl)-1-[(4-methoxyphenyl)sulfonyl]-4-piperidine carboxylic acid was prepared following the procedure of Example 64 (step 5). Starting from methyl 4-(4-but-2-ynyloxybenzenesulfonyl)-1-[(4-methoxyphenyl)sulfonyl]-4-piperidinecarboxylate (545 mg, 1.04 mmol) in 8 ml of tetrahydrofuran:methanol (1:1), and 1N sodium hydroxide (2.09 ml, 2.09 mmol) to obtain 446 mg (85%) of the acid. HR-MS: m/z Calculated for C23H25NO8S2 508.1094; Found 508.1073.
