CAS 356783-16-9: 3,6-dichloropyrazine-2-carbonitrile

3,6-Dichloropyrazine-2-carbonitrile

3,6-Dichloropyrazine-2-carbonitrile is a synthetic nucleophilic compound that can be used to produce antiviral drugs. This chemical belongs to the class of chlorination compounds and reacts with nucleophiles in a nucleophilic substitution reaction. 3,6-Dichloropyrazine-2-carbonitrile has been optimized for synthesis by recrystallization and solvents. The reactants are heated and then mixed, where it undergoes an acid catalyzed hydrolysis followed by a dehydration reaction. 3,6-Dichloropyrazine-2-carbonitrile is synthesized by reacting a nitrile with phosgene to form the chloroformate ester which is reacted with ammonia or amines. The final product is purified using recrystallization or solvent extraction.
