| Abstract: | New 4-(N-arylamino)-2-(1H-pyrazol-1-yl)pyrimidine derivatives were synthesized, and the UV, IR, and PMR spectra of solutions of them in CHCl3, CCl4 and d6-DMSO were studied. The questions of intermolecular association and conformational isomerism are discussed.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 8, pp. 1114–1119, August, 1980. |
