Reaction Steps
N′-Acetyl-6-chloronicotinohydrazide (95 mg, 0.45 mml) and 3,3,3-triethyl-1-(methoxycarbonyl)diazathian-3-ium-1-ide 2,2-dioxide (159 mg, 0.67 mmol) were taken up in tetrahydrofuran (4.5 mL) and heated in a microwave at 120° C. for 30 minutes. The reaction was then diluted with ethyl acetate and washed with saturated aqueous ammonium chloride, water, and brine. The organic layer was dried over magnesium sulfate, filtered, and concentrated in vacuo to afford the title compound.
