A Novel and Convenient Synthesis of 2-Amino-3-Cyano-5-N-Substituted Piperazinyl Pyridines
摘要:
A mixture of two moles of triethylorthoacetate, one mole of malononitrile and one mole of N-substituted piperazine in the presence of excess of ammonium acetate at reflux conditions affords the title compounds. Elemental and spectral data confirms the structures of the purified compounds.
