stirrer at room temperature under neat reaction condition for 5 to 10 hrs. Results: After purification by column chromatography using silica gel(60-120 mesh) and pet-ether, ethylacetate mixture as eluent, we achieved pyrazinederivatives from moderate to high yield. Conclusion: Efficient and clean procedure for one-pot preparation of pyrazines from ethylenediamine and 1,2-diketones or with α-hydroxy ketone
