Roman, Gh. et al. published their research in Chemistry of Heterocyclic Compounds in 2002 | CAS: 15953-73-8

4-Chloro-3,5-dimethyl-1H-pyrazole (cas: 15953-73-8) belongs to pyrazole derivatives. Pyrazoles, a five-membered heterocycle containing two adjacent nitrogen atoms, are the core structures found in a number of molecules that possess a wide range of pharmaceutical and agricultural activities. Pyrazole the presence of this nucleus in pharmacological agents of diverse therapeutic categories such as celecoxib, a potent anti-inflammatory, the antidepressant agent fezolamide have proved the pharmacological potential of the pyrazole moiety.

Synthesis and reactivity of Mannich bases. 10. N-Alkylation of pyrazoles with Mannich bases derived from ortho-hydroxyacetophenones was written by Roman, Gh.;Comanita, E.;Comanita, B.. And the article was included in Chemistry of Heterocyclic Compounds (New York, NY, United States)(Translation of Khimiya Geterotsiklicheskikh Soedinenii) in 2002.Electric Literature of C5H7ClN2 This article mentions the following:

The involvement of Mannich bases derived from ortho-hydroxyacetophenones in amine-exchange reactions with pyrazole and methyl- and/or halogen-substituted pyrazoles was studied. The corresponding β-(pyrazol-1-yl)ethyl ketones (I; R1, R2 = H, Me; R3 = H, Cl, I, NO2) were obtained in excellent yield and were characterized by elemental anal., IR, and 1H and 13C NMR spectroscopy. In the experiment, the researchers used many compounds, for example, 4-Chloro-3,5-dimethyl-1H-pyrazole (cas: 15953-73-8Electric Literature of C5H7ClN2).
