Abstract
The new pyrazine derivatives exhibited an antibacterial activity have been synthesized. In present investingation, we reported here the synthesis of pyrazolines from piperazine chalcones and hydrazine hydrate in basic condition using methanolas a solvent for the reaction. These synthesized compounds were established on the basis of IR, 1HNMR, Mass spectroscopic data .
