Pymetrazine is chosed as the lead compound, and 21 compounds were firstly designed and synthesized. These compounds were characterized by introducing phenyl derivatives with different functional groups to replace pyridine ring with the isosteric principle and the method of homogeneous synthesis and reasonable biologically designing in order to find new compounds with potential biological activity. These compounds were confirmed by IR, H NMR and MS spectra.
