Аннотация:The behavior of <i>N</i>-Substituted 3,5-dimethyl-4-nitroso-1<i>H</i>-pyrazoles in oxidation, condensation, and reduction reactions was studied. The synthesized 4-aminopyrazole was acylated and diazotized with further azo coupling or the replacement of the amino group by iodine, as well as subjected to condensation with 4-nitrobenzaldehyde. The first condensation of nitrosopyrazole with 2,4-dinitrotoluene was demonstrated. As a result, new functionalized pyrazole derivatives were isolated. The structure of the novel pyrazoles was confirmed by IR and <sup>1</sup>H and <sup>13</sup>C NMR spectroscopy, gas chromatography-mass spectrometry, and elemental analysis. The synthesized compounds hold promise for further research in medicine and pharmaceutical chemistry.
