For the previously obtained 1-isopropyl-3-α-naphthyl-5-methoxymethyl-4-nitrosopyrazole, a reduction reaction with hydrazine hydrate was performed. It was first synthesized by 1-isopropyl-3-α-naphthyl- 5-methoxymethyl-4-aminopyrazole which was then sulfonylated by p-acetamidobenzenesulfonyl chloride and p-toluenesulfonic chloride. As a result previously unknown sulfonylated derivatives of N-alkylated aminopyrazoles were obtained. The composition and structure are confirmed by modern methods of analysis such as IR, 1H NMR spectroscopy and mass spectrometry
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
