Reaction Steps

To a solution of (E)-4-(acetylsulfanyl)-3-[(1-{4-[N-(t-butyldimethylsilyloxy)carbamoyl]butyl}-1H-1,2,3-triazol-4-yl)methylidene]-1-[2-cyclopropyl-1-(2-fluorophenyl)-2-oxoethyl]piperidine (148 mg) in dichloromethane (3 ml) was added 4N solution of hydrogen chloride in dioxane (230 μl) at 0° C. The resulting mixture was stirred at room temperature for 15 minutes. The solvent and excess hydrogen chloride were removed in vacuo, and the residue was purified by chromatography on silica gel using a mixture of methanol and dichloromethane (3:97 to 15:85) as the eluent to afford (E)-4-(acetylsulfanyl)-1-[2-cyclopropyl-1-(2-fluorophenyl)-2-oxoethyl]-3-({1-[4-(N-hydroxycarbamoyl)butyl]-1H-1,2,3-triazol-4-yl}methylidene)piperidine hydrochloride (110 mg).
