Acetyl chloride → N-(5,6-dichloro-3-nitropyrazin-2-yl)acetamide

Participants

Reaction Steps

To 1.0 g of 5,6-dichloro-3-nitropyrazinamine in 15 ml acetyl chloride under nitrogen atmosphere at room temperature is added 0.84 g anhydrous sodium bicarbonate. The reaction mixture is then stirred and heated at reflux for 4 days. Excess acetyl chloride is then removed in vacuo and the residue is chromatographed on silica gel. The desired product is eluted from the column with chloroform.
