Reaction Steps

4-(4-But-2-ynyloxy-phenylsulfanyl)-4-hydroxycarbamoyl-piperidine-1-carboxylic acid tert-butyl ester, prepared by the method outlined in Example 14 (Step 3) (0.175 g, 0.4 mmol), was treated with 4N hydrochloric acid in dioxane (5 mL) at 25 ° C. for 1 h 15 min. The reaction mixture was concentrated in vacuo, diethyl ether was added and the resulting precipitate isolated by filtration to give 4-(4-but-2-ynyloxy-phenylsulfanyl)-piperidine-4-carboxylic acid hydroxyamide as a white solid (0.12 g). Electrospray Mass Spectroscopy: ((M+H)+=321)
