Versuchsvorschrift
5-Chloro-thiophene-2-carboxylic acid {2-[carbamoylmethyl-(1-isopropyl-piperidin-4-yl)-sulfamoyl]-ethyl}-amide was prepared by an analogous procedure as described in example 15 starting from 48 mg (2 equiv.) 2-chloro-acetamide and 100 mg (0.25 mmol) 5-chloro-thiophene-2-carboxylic acid [2-(1-isopropyl-piperidin-4-ylsulfamoyl)-ethyl]-amide. Final purification by preparative RP-HPLC (CH3CN/H2O gradient+0.1% TFA) gave pure 5-chloro-thiophene-2-carboxylic acid {2-[carbamoylmethyl-(1-isopropyl-piperidin-4-yl)-sulfamoyl]-ethyl}-amide. The title compound was obtained as its trifluoroacetate in form of a colorless amorphous material.
