5-Hexyl-3-<2-(1H-pyrazol-1-yl)pyrimidin-4-yl>amino-1(2)H-1,2,4-triazoles and 2-(3,5-dipropyl-4-ethyl-1H-pyrazol-1-yl)-6-methyl-4-(5-methyl-1H-pyrazol-1-yl)aminopyrimidine were synthesized by the reaction of 4-chloropyrimidines with 3-amino-5-hexyl-1H-1,2,4-triazole and 3-amino-5-methyl-1H-pyrazole.Their IR, UV, and PMR spectra were investigated.New methods for the preparation of the intermediates, viz., 2-hydrazino-4(3H)-pyrimidinones and 2-(1H-pyrazol-1-yl)-4(3H)-pyrimidinones, that make it possible to obtain these compounds in higher yields are described.
