1.1 g 4-[2-(5-Chloro-2-methoxy-benzoylamino)-ethyl]-benzenesulfonyl chloride, 483 mg 5-Cyclopropyl-[1,3,4]thiadiazol-2-ylamine and 35.0 mg 4-dimethylaminopyridine were dissolved in 5 ml pyridine and stirred under microwave irradiation at 115° C. for two hours. The pyridine was removed in vacuo and the residue coevaporated three times with portions of 20 ml toluene. The residue was purified by RP-HPLC to obtain 590 mg 5-Chloro-N-{2-[4-(5-cyclopropyl-[1,3,4]thiadiazol-2-ylsulfamoyl)-phenyl]-ethyl}-2-methoxy-benzamide.
