Reaction Steps

To a 20 ml scintillation vial was added 5-(aminosulfonyl)-2,3-dichlorobenzoic acid (40 mg, 0.148mmol) and commercially available 5-(4-fluorophenyl)-1,3,4-thiadiazol-2-amine (28.9 mg, 0.148 mmol). To this was added EDC (28 mg, 0.148 mmol) and HOAt (20 mg, 0.148 mmol) followed by 3 ml DCM. The reaction mixture was stirred with a Teflon covered magnetic stir-bar at room temperature for overnight. The product was collected by vacuum filtration and air dried, yielding 5-(aminosulfonyl)-2,3-dichloro-N-[5-(4-fluorophenyl)-1,3,4-thiadiazol-2-yl]benzamide (31 mg, 47%) as light tan solid.
