Conditions for the metalation of 2,6-dichloro- and 2,6-dimethoxy-pyrazine are defined and the lithio-derivatives are shown to react with some electrophiles. A convenient synthesis of a diazaxanthone from the lithio-derivative of the dichloro-compound is described. Couplings between phenylacetylene and iodo-derivatives of pyrazine have been carried out.
