Hot sale 875781-17-2 Top quality 5-Bromo-1H-pyrazolo[3,4-b]pyridine manufacturer

5-bromo-1H-pyrazolo [3,4-B] pyridine Chinese alias 5-bromopyrazolo [3,4-b] pyridine, pyrazolo [3,4-B] pyridine compound is a very important kind of thick heterocyclic ring, due to its specific physiological activity and structural similarity with indole, azafindole, etc., it has aroused widespread interest and is a very important type of dense heterocyclic compound. They have good curative effects in the prevention and treatment of gram-negative and positive bacteria, tumors and cancers, asthma, neurological diseases, osteoporosis and Alzheimer's disease, and have a wide range of applications in the fields of pharmaceuticals, pesticides and dyes.

When synthesizing pyrazolopyridine compounds with pyridine ring as the parent ring, hydrazine or substituted hydrazine is generally used to close the ring. If 3, 6-dichloro-2-pyridine formaldehyde reacts with hydrazine to undergo bromination reaction, 5-bromo-1H-pyrazolo [3,4-B] pyridine can be prepared. In addition, 5-bromo-1H-pyrazolo [3,4-b] pyridine can be synthesized from 2-fluoro -5-bromopyridine -3-formaldehyde in a yield of about 46%; or 5-bromo-1H-pyrazolo [3,4-b] pyridine can be synthesized from 3-aminopyrazole and 2-bromomalondialdehyde in a yield of about 11%; in this paper, 5-bromo-2-hydrazinylpyridine hydrochloride is used as the starting material to prepare 5-bromo-1H-pyrazolo [3,4-B] pyridine by intramolecular ring-forming reaction. The preparation reaction formula is as follows. Fig. 1 5-bromo-1H-pyrazolo [3,4-B] pyridine preparation reaction formula
