2-Amino-6-bromopyridine (CAS# 19798-81-3) Information

Overview 2-amino inotsiva nitrogen-ine nhanhatu-membered heterocyclic compounds ine zvakakosha mashandisirwo muindasitiri yemakemikari, senge 2-amino -6-Bromopyridine ndechimwe chezvimiro zvakakosha mumishonga yekugadzira uye mamorekuru emakemikari ekurima, uye anoshandiswa zvakanyanya mukugadzira. zvechisikigo zvigadzirwa, zvinodhaka, luminescent zvinhu uye akasiyana makemikari akanaka.
Application 2-amino inotsiva nitrogen-ine nhanhatu-membed heterocyclic makomisheni ane zvakakosha mashandisirwo muindasitiri yemakemikari, senge 2-amino -6-Bromopyridine ndechimwe chezvimiro zvakakosha mumishonga yekugadzira uye mamorekuru emakemikari ekurima, uye anoshandiswa zvakanyanya mukugadzira. zvechisikigo zvigadzirwa, zvinodhaka, luminescent zvinhu uye akasiyana makemikari akanaka.
Kugadzirira Kugadzirira kwe2-amino-6-bromopyridine: Wedzera 2-fluoro-6-bromo-pyridine (1mmol), pentamidine hydrochloride (2mmol), sodium tert-butoxide (3mmol), HO (0.5mL) uye diethylene glycol dimethyl ether (2.5) mL) mune 25 ml reaction chubhu. Maitiro akaitwa pa150 ℃ kwemaawa makumi maviri nemana. Mushure mekupedzwa kwekuita, yakatonhodzwa kusvika kune tembiricha yekamuri. Wedzera 10mL ye ethyl acetate kuti udzime maitiro, wedzera 6mL yemvura yakanyungudutswa yemunyu kuti usuke, iparadzanise chikamu chehupenyu, wozobvisa chikamu chemvura ne ethyl acetate kwe3 nguva (yero ye ethyl acetate nguva imwe neimwe i6mL) uye batanidza organic. chikamu, wedzera anhydrous sodium sulfate kuti iome, bvisa iyo inonyungudutsa inosanganisira organic solvent uye inorganic solvent ne vacuum. distillation, wozopatsanura organic solvent necolumn chromatography kuti uwane chinongedzo chigadzirwa 2-amino-6-bromopyridine ine goho re93%.
use mishonga yepakati.
nokuda kwekugadzirisa kwakanaka kwe7-azafindole muhari imwe; yekugadzirwa kwemishonga inorwisa HIV
