Reaction Steps

5-Bromo-furan-2-carboxylic acid [2-(1-isopropyl-piperidin-4-ylsulfamoyl)-ethyl]-amide was prepared by an analogous procedure as described in example 9 starting from 126 mg (1.1 equiv.) 5-bromo-furan-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-bromo-furan-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. Yield: 121 mg MS (ES+): m/e=422, bromo pattern.
