Synthesis of some new fluorine‐containing 5‐amino‐1,3‐disubstituted pyrazoles and 1<i>H</i>‐pyrazolo[3,4‐<i>b</i>]pyridines

Abstract

Abstract Nine new fluorine containing 5‐amino‐1,3‐disubstituted pyrazoles have been synthesized and characterized by spectral studies. Condensation reactions of these 5‐amino‐1,3‐disubstituted pyrazoles with fluorinated 1,3‐diketones in the presence of glacial acetic acid have been studied and the structures of the resulting 1 H ‐pyrazolo[3,4‐ b ]pyridines have been confirmed by ir, pmr and 19 F nmr spectral studies.
