| titleOfInvention | A kind of synthetic method of 3-amino-4-iodo-indazole |
| abstract | The invention discloses a method for synthesizing 3-amino-4-iodo-indazole. 3-amino-4-iodo-indazole is an important drug synthesis intermediate and has great development prospects in the future. The present invention The invention uses 2,6-difluorobenzonitrile as a raw material to obtain a high-quality and mature synthetic process through a large number of experiments. 2,6-difluorobenzonitrile is treated with ammonia water under certain conditions to obtain 2-amino-6 -Fluorobenzonitrile, 2-amino-6-fluorobenzocyanide is treated with diazotization and cuprous iodide to obtain 2-fluoro-6-iodobenzonitrile, and the resulting 2-fluoro-6-iodobenzonitrile and Hydrazine hydrate reaction can give 3-amino-4-iodo-indazole. |
