Reaction Steps

(E)-4-Cyano-2-(2-(3,4-dichlorophenyl)vinylsulfonamido)benzenesulfonamide (123 mg, 0.28 mmol), sodium acetate (93 mg, 1.14 mmol) and para-toluenesulfonhydrazide (212 mg, 1.14 mmol) were dissolved in anhydrous tetrahydrofuran (3 mL) in a microwave vial. The vial was capped and evacuated two times with argon. The mixture was heated in a microwave at 180° C. for 15 min. The mixture was filtered and the solvent was evaporated in vacuo. Purification twice by preparative HPLC gave 4.8 mg (4% yield) of the title compound.
