To a solution of tert-butyl 4-{[5-cyano-2-(3,5-dichlorophenoxy) phenyl]sulfonyl}-3-(1H-1,2,4-triazol-1-ylmethyl)-1-piperazinecarboxylate (37 mg, 0.06 mmol) in CH2Cl2 (1 ml) was added 4N HCl in 1,4-dioxane (1 ml). The mixture was stirred for 2 hours at room temperature. The solvent was evaporated in vacuo, the residue was triturated with Et2O and the white solid was collected by filtration to give 4-(3,5-dichlorophenoxy)-3-{[2-(1H-1,2,4-triazol-1-ylmethyl)-1-piperazinyl]sulfonyl}benzonitrile hydrochloride (28.5 mg, 86.3%).
