Versuchsvorschrift

5-(N-(4-(dimethylcarbamoyl)phenyl)sulfamoyl)thiophene-2-carboxylic acid (Int. 76) (54 mg, 0.152 mmol), DMAP (6.20 mg, 0.051 mmol), and EDC (38.9 mg, 0.203 mmol) were dissolved in DMF. (S)-3,5-dichloro-4-(2-(3-(cyclopropylmethoxy)-4-(difluoromethoxy)phenyl)-2-hydroxyethyl)pyridine 1-oxide (42.7 mg, 0.102 mmol) was added. The reaction was stirred at RT for 4 hours. The reaction mixture was diluted with water and extracted with AcOEt. The organic phase was dried over Na2SO4 and concentrated under vacuum to give a crude product which was purified by preparative HPLC-Method 2 to give 10 mg of the desired product (Compound 77).
