Category: 1940-27-8

1940-27-8, name is 4-Bromo-2,5-dichloroaniline, belongs to chlorides-buliding-blocks compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. SDS of cas: 1940-27-8

General procedure: A mixture of corresponding chloro derivative (IV) (4.2 mmol), the appropriate amine (4.2 mmol) and triethylamine (8.4 mmol) in dry acetonitrile was refluxed for 4 hours. The mixture was cooled, poured on crushed ice and filtered. The residue was washed with cold water and dried. The crude product was recrystallized from ethanol to get the titled compounds.

The synthetic route of 1940-27-8 has been constantly updated, and we look forward to future research findings.
