| | 4-Chloronicotinic acid Usage And Synthesis |
| Chemical Properties | White to light brown solid | | Uses | 4-Chloronicotinic Acid is a building block used in a synthesis of benzocanthinones via tributyltin hydride radical induced cyclization. It is also used in a synthesis of heterocyclic analogues of xanthone. | | Uses | Building block used in a synthesis of benzocanthinones via tributyltin hydride radical induced cyclization. Also used in a synthesis of heterocyclic analogues of xanthone. | | Synthesis | 1. Neutralization reaction: Neutralize 4-chloropyridine hydrochloride using 10% NaOH solution to obtain 4-chloropyridine (1).
2. lithiation reaction: 4-chloropyridine (1) (15 mmol) was dissolved in THF (250 ml) under nitrogen protection, cooled to -78 °C, and 1.2 equivalents of lithium diisopropylammonium was slowly added (1.5 M hexane solution containing 1 equivalent of THF, ALDRICH).
3. carboxylation reaction: the resulting anion is reacted with dry CO to produce 4-chloropyridine-3-carboxylic acid (3, i.e. 4-chloronicotinic acid).
4. Isolation and purification: The reaction mixture was treated and isolated to obtain 4-chloronicotinic acid as a colorless solid in 60-80% yield. | | References | [1] Journal of Organic Chemistry, 1995, vol. 60, # 2, p. 292 - 296
