4-Chloro-N-[2-(1-isopropyl-piperidin-4-ylsulfamoyl)-ethyl]-benzamide was prepared by an analogous procedure as described in example 9 starting from 104 mg (1.1 equiv.) 4-chloro-benzoic acid and 150 mg (0.60 mmol) 2-amino-ethanesulfonic acid (1-isopropyl-piperidin-4-yl)-amide. Final purification by preparative RP-HPLC (CH3CN/H2O gradient+0.1% TFA) gave pure 4-chloro-N-[2-(1-isopropyl-piperidin-4-ylsulfamoyl)-ethyl]-benzamide. The title compound was obtained as its trifluoroacetate in form of a colorless amorphous material.
