Abstract
Four new piperazine derivatives,1-{ 2-[4-(2-substituent group) piperazin-1-yl]ethyl }guanidine sulfate and 1-(2-hydroxyethyl)-4-methylpiperazine,were synthesized by connection of substituted piperazine with guanidyl or hydroxyl based the splicing principle of active groups.The structures were characterized by1 H NMR,13 C NMR,ESI-MS.
