General Description
2-Amino-3,5-dibromopyrazine can be synthesized from 2-aminopyrazine via bromination using
N-bromosuccinimide (NBS). It reacts with sodium dicyanocuprate to form a mixture of mono and dicyanation products. The formation of 2-aminothiazolopyrazines by reacting 2-amino-3,5-dibromopyrazine with isothiocyanates has been reported.
