Reaction Steps

4-(4-but-2-ynyloxy benzenesulfonyl)-N-hydroxy-1-[(trifluoromethyl)sulfonyl]-4-piperidinecarboxamide was prepared following the procedure Example 64 (step 6). Starting from 4-(4-but-2-ynyloxybenzenesulfonyl)-1-[(trifluoromethyl)sulfonyl]-4-piperidinecarboxylic acid (145 mg, 0.31 mmol) in dimethylformamide (3 ml), 1-hydroxybenzotriazole (50 mg, 0.37 mmol), 1-[3-(dimethylamino)propyl]-3-ethylcarbodiimide hydrochloride (83 mg, 0.47 mmol), N-methylmorpholine (0.051 ml, 0.47 mmol), and hydroxylamine (0.095 ml, 1.55 mmol), 90 mg (60%) of the product was isolated as a solid. HR—MS: m/z Calculated for C17H19F3N2O7S2 485.0659; Found 485.0666.
