Dulmar 2-amino beddelka nitrogen-ka kooban lix-xubnood heterocyclic xeryahooda codsiyada muhiimka ah ee warshadaha kiimikada, sida 2-amino -6-Bromopyridine waa mid ka mid ah qaab-dhismeedka muhiimka ah ee dawooyinka synthetic iyo molecules kiimikada beeraha, waxaana si weyn loo isticmaalaa in synthesis. ee alaabta dabiiciga ah, daawooyinka, alaabta luminescent iyo kiimikooyinka kala duwan ee wanaagsan.
Codsiga 2-amino beddelka nitrogen-ka kooban lix-xubnood heterocyclic xeryahooda codsiyada muhiimka ah ee warshadaha kiimikada, sida 2-amino -6-Bromopyridine waa mid ka mid ah qaab-dhismeedka muhiimka ah ee dawooyinka synthetic iyo molecules kiimikada beeraha, oo si weyn loo isticmaalo in synthesis. ee alaabta dabiiciga ah, daawooyinka, alaabta luminescent iyo kiimikooyinka kala duwan ee wanaagsan.
Diyaarinta Diyaarinta 2-amino-6-bromopyridine: Ku dar 2-fluoro-6-bromo-pyridine (1mmol), pentamidine hydrochloride (2mmol), sodium tert-butoxide (3mmol), HO (0.5mL) iyo diethylene glycol dimethyl ether (2.5). mL) ku jira tuubo falcelin 25 ml ah. Dareen-celinta waxaa lagu sameeyay 150 ℃ 24 saacadood. Ka dib markii falcelinta la dhammeeyo, waxaa lagu qaboojiyey heerkulka qolka. Ku dar 10mL oo ah ethyl acetate si aad u damiso falcelinta, ku dar 6mL oo biyo cusbo ah oo buuxa si aad u dhaqdo, kala saar wajiga organic, ka dibna soo saar wajiga aqueous leh ethyl acetate 3 jeer (qiyaasta ethyl acetate mar kasta waa 6mL) oo isku dar organic. Marxaladda, ku dar sulfate sodium anhydrous si ay u engegto, ka saar dareeraha oo ay ku jiraan dareeraha organic iyo dareeraha aan organic by vacuum distillation, iyo dabadeed kala saar dareeraha organic by chromatography column si aad u hesho badeecada la beegsanayo 2-amino-6-bromopyridine oo leh 93%.
isticmaal dhexdhexaadiyeyaasha dawooyinka.
loogu talagalay isku-dhafka waxtarka leh ee 7-azafindole ee hal dheri; loogu talagalay isku dhafka daawooyinka ka hortagga HIV
