Chemistry of Heterocyclic Compounds Aims and scope

Abstract

A method was developed for the synthesis of 3(5)-aminopyrazole, 1-phenyl-5-aminopyrazole, and 1-ethyl-3-aminopyrazole by reaction of α-chloroacrylonitrile with the appropriate hydrazines. The corresponding addition products -3-(2,2-dimethylhydrazino)- and 3-(2-phenylhydrazino)-2-chloropropionitriles — were isolated in the case of 1,1-dimethylhydrazine and phenylhydrazine.
