Analyzing the synthesis route of 337958-60-8

The synthetic route of 337958-60-8 has been constantly updated, and we look forward to future research findings.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.337958-60-8,5,7-Dichloro-1,6-naphthyridine,as a common compound, the synthetic route is as follows.

A mixture of 5,7-dichloro-1,6-naphthyridine (4.0 g, 20 mmol) and Niodosuccinimide (9.0 g, 37 mmol) in acetic acid (100 mL) was heated at reflux for 12 h. The reaction mixture was concentrated under vacuum, and the residue was purified by column chromatography 20:1 petroleum ether:EtOAc to provide the title intermediate as ayellow solid (2.4 g, 37 % yield).

The synthetic route of 337958-60-8 has been constantly updated, and we look forward to future research findings.
