Abstract The pharmacodynamic properties1-3 of substituted amino pyrazines as well as their importance in the synthesis of pteridine and other polyfused heterocyclic systems is well known4,5. In this investigation we aim to prepare a new series of condensed heterocyclic systems containing the pyrazine nucleus.
