Chemical Properties

light yellow to purple or light brown powder or

Uses

2,3-Diamino-5-bromopyridine may be used in the preparation of the following heterocyclic compounds:

6-bromoimidazo-[b]pyridine
11-bromopyrido[2′,3′:5,6]pyrazino[2,3-f][1,10]phenanthroline
6-bromo-3-(tetrahydro-2H-pyran-2-yl)-3H-imidazo[4,5-b]pyridine

General Description

2,3-Diamino-5-bromopyridine can be prepared from 2-amino-3-nitro-5-bromopyridine via reduction using stannous chloride.

Synthesis

6945-68-2

38875-53-5

The general procedure for the synthesis of 2,3-diamino-5-bromopyridine from 2-amino-3-nitro-5-bromopyridine is as follows: Part I: Synthesis of imidazo[4,5-b]pyridin-2(3H)-one boronic acid Step 1: Preparation of 5-bromopyridine-2,3-diamine 5-Bromo-3-nitropyridin-2-amine (3 g) was dissolved in a solvent mixture of isopropanol (56 mL) and water (28 mL). Ammonium chloride (1.47 g, 2 eq.) and iron powder (2.31 g, 3 eq.) were subsequently added. The reaction mixture was heated to 90°C and kept at this temperature for 45 minutes. Upon completion of the reaction, the mixture was cooled, diluted with ethyl acetate (EtOAc), filtered to remove insoluble matter, and the organic and aqueous layers were separated. The organic layer was subsequently washed with saturated brine, dried over anhydrous sodium sulfate and concentrated under reduced pressure to afford the target product 2,3-diamino-5-bromopyridine as a solid (2.45 g, 95% yield). Product characterization data: 1H-NMR (300 MHz, DMSO-d6) δ 7.25 (d, 1H), 6.77 (d, 1H), 5.70-5.40 (bs, 2H), 5.20-4.80 (bs, 2H).
