Procedure

In a solution of 5-amino-4-(4-cyclopropylnaphthalen-1-yl)-4H-[1,2,4]triazole-3-thiol (708 mg, 2.5 mmol), K2CO3 (380 mg, 2.5 mmol) in DMF (20 mL) was added 2-chloro-N-(2-chloro-4-sulfamoylphenyl)acetamide (710 mg, 2.5 mmol). The reaction mixture was stirred at room temperature overnight. Upon completion of the reaction, the solvent was evaporated. The residue was purified by silica gel chromatography to yield 2-[5-Amino-4-(4-cyclopropylnaphthalen-1-yl)-4H-[1,2,4]triazol-3-ylsulfanyl]-N-(2-chloro-4-sulfamoylphenyl)acetamide (1.26 g, 95%).
