N-{2-[4-(4-fluorobenzoyl)piperidino]ethyl}-4-(N-hydroxyimino)-N-(2-methoxyphenyl)benzenesulfonamide (65 mg, 0.12 mmol) was dissolved in methylene chloride (2 ml) to which was subsequently added saturated hydrogen chloride/ether solution (1 ml). After 5 minutes of stirring, the solvent was removed by evaporation, and the resulting residue was solidified in ether (5 ml) and collected by filtration to obtain 69 mg (99.8%) of the title compound in a colorless amorphous powder form.
