Syntheses and properties of silver salt of pyrimidine derivative -Kristafone
For the first time, the silver salt of the pyrimidine derivative N-(6-methyl-2,4-dioxo-1,2,3,4-tetrahydro-5H-pyrimidine-4-sulfon)-N-isonicotinoylhydrozide (Kristafone) has been synthesized. The physical-chemical and spectral properties of the salt as well as the structure and chemical composition of its molecule has been studied by means of elemental, titrimetric analyses and IR, H<sup>1</sup>, C<sup>13</sup> spectra. The silver salt has been established to possess higher biological activity than initial pyrimidine.
