実験手順

5-Methyl-thiophene-2-carboxylic acid [2-(1-isopropyl-piperidin-4-ylsulfamoyl)-ethyl]-amide was prepared by an analogous procedure as described in example 9 starting from 94 mg (1.1 equiv.) 5-methyl-thiophene-2-carboxylic 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 5-methyl-thiophene-2-carboxylic acid [2-(1-isopropyl-piperidin-4-ylsulfamoyl)-ethyl]-amide. The title compound was obtained as its trifluoroacetate in form of a colorless amorphous material, which turned out to be hygroscopic with time.
