Abstract
Alkyl derivatives of 2-(1-pyrazolyl)-4(3H)-pyrimidinone were synthesized and converted to 4-chloro-, 4-arylamino-, and 4-hydrazino-2-(1-pyrazolyl)pyrimidines. The corresponding hydrazones were obtained by reaction of 5-ethyl-2-hydrazino-6-methyl-2-(4-ethyl-3,5-di-n-propylpyrazolyl) pyrimidine with isatin and salicylaldehyde. The UV and IR spectra of the synthesized compounds were studied. It was established that the hydrazones contain intra-molecular hydrogen bonds.
