A common heterocyclic compound, the naphthyridine compound, name is 2,7-Naphthyridin-1-amine,cas is 27225-00-9, mainly used in chemical industry, its synthesis route is as follows.
4-Bromo-2,7-naphthyridin-1-ylamine32 g of 2,7-naphthyridin-1-ylamine is dissolved in 200 ml of acetic acid at room temperature. 35 g of bromine in 200 ml of acetic acid are then added slowly that the temperature does not exceed 25. The mixture is stirred for a further 60 minutes.The suspension obtained is dissolved in 500 ml of water, and the pH is adjusted to pH 7-8 using 500 ml of 25% aqueous ammonia solution.The mixture is stirred for 14 h. The brown precipitate is filtered off, washed with water and dried, giving 28.3 g of crude product. Purification by flash chromatography in ethyl acetate/methanol gives 18.5 g of 4-bromo-2,7-naphthyridin-1-ylamine, M224.06 g/mol, M+H found 224.
27225-00-9, As the rapid development of chemical substances, we look forward to future research findings about 27225-00-9
