As a common heterocyclic compound, it belong naphthyridine compound,4-Bromo-2,7-naphthyridin-1-amine,959558-28-2,Molecular formula: C8H6BrN3,mainly used in chemical industry, its synthesis route is as follows.,959558-28-2

4-(1-Benzenesulfonyl-2-methyl-1H-pyrrolo[2,3-b]pyridin-3-yl)-2,7-naphthyridin-1-ylamine23.7 g of tripotassium phosphate and 3.2 g of trans-dichlorobis(tricyclohexyl-phosphine)palladium(II) are added to a solution of 12.5 g of 4-bromo-2,7-naphthyridin-1-ylamine in 400 ml of diglyme and 15 ml of water. The mixture is heated to 125, and 25 g of 1-(benzenesulfonyl)-2-methyl-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrrolo[2,3-b]pyridine in 100 ml of diglyme are added dropwise over the course of 30 minutes. The mixture is stirred at 125 for 3 h, at room temperature for 20 h and the solvent is subsequently removed and the mixture is subjected to conventional work-up. The product is purified by means of flash chromatography over 330 g of silica with a methanol gradient in ethyl acetate with 200 ml/min with UV detection at 254 nm, giving a pure fraction (5.1 g) and a contaminated fraction (6.5 g) of 4-(1-benzenesulfonyl-2-methyl-1H-pyrrolo[2,3-b]pyridin-3-yl)-2,7-naphthyridin-1-ylamine, M415.47 g/mol, M+H found 416.

With the synthetic route has been constantly updated, we look forward to future research findings about 4-Bromo-2,7-naphthyridin-1-amine,belong naphthyridine compound
