Reaction Steps

5-Chloro-thiophene-2-carboxylic acid [3-(1-isopropyl-piperidin-4-ylsulfamoyl)-propyl]-amide was prepared by an analogous procedure as described in example 5 iii) starting from 120 mg (1 equiv.) 5-chloro-thiophene-2-carboxylic acid and 195 mg (0.74 mmol) 3-amino-propane-1-sulfonic acid (1-isopropyl-piperidin-4-yl)-amide. Final purification by preparative RP-HPLC (CH3CN/H2O gradient+0.1% TFA) gave pure 5-chloro-thiophene-2-carboxylic acid [3-(1-isopropyl-piperidin-4-ylsulfamoyl)-propyl]-amide. The title compound was obtained as its trifluoroacetate in form of a colorless amorphous material.
