| | Pyridazine, 3-bromo- (9CI) Usage And Synthesis |
| Description | 3-Bromopyridine can undergo lithiation with LDA at low temperatures in the 4-position: Heterocycles, involved in formation of the Grignard by Mg exchange with i-PrMgCl and in transmetallation of the lithiated derivative with zinc chloride followed by treatment with an electrophile as a route to 4-substituted 3-bromopyridines1-4. 3-Bromopyridine is also used as an intermediate in the synthesis of Active Pharmaceutical Ingredients especially Abiraterone acetate (an antiandrogen medication which is used in the treatment of prostate cancer) and Zimelidine (selective serotonin reuptake inhibitor (SSRI) antidepressants)5.
