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

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 1H‐pyrazolo[3,4‐b]pyridines have been confirmed by ir, pmr and 19F nmr spectral studies.
