Name is 2,5-Dichloro-1,8-naphthyridine, as a common heterocyclic compound, it belongs to naphthyridine compound, and cas is 91870-15-4, its synthesis route is as follows.,91870-15-4

Example 2 Preparation of 5-chloro-2-phenyl-1,8-naphthyridine 19.7 mg (0.028 mmol) of bis(triphenylphosphine)palladium(II) chloride are added to a suspension of 279 mg (1.40 mmol) of 2,5-dichloro-1,8-naphthyridine, 171 mg (1.40 mmol) of benzeneboronic acid and 141 mg (1.68 mmol) of sodium hydrogencarbonate in 2.8 ml of DMF and 1.4 ml of water, and the mixture is heated to 80¡ã C. under nitrogen. The reaction mixture is stirred at this temperature for 23 hours. The reaction mixture is evaporated and chromatographed on a silica-gel column with ethyl acetate/petroleum ether as eluent: 5-chloro-2-phenyl-1,8-naphthyridine as colourless solid; MS (EI) 240 [M]+; 1H-NMR (CDCl3, 300 MHz): delta [ppm]=9.02 (d, J=4.7 Hz, 1H), 8.65 (d, J=8.7, 1H), 8.35-8.30 (m, 2H), 8.11 (d, J=8.7, 1H), 7.57-7.52 (m, 3H).

91870-15-4, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 2,5-Dichloro-1,8-naphthyridine, cas is 91870-15-4,the naphthyridine compound, it is a common compound, a new synthetic route is introduced below.

The product from Example 21d (0.67 g, 3.36 mmol) and the product from Example9c (0.78 g, 3.36 mmol) in 10 mL ethanol were heated under reflux for 5.5 hr. The reaction mixture was cooled to room temperature and the solvent was removed concentrated under vacuum leaving yellow solid that was used without further purification (1.43 g, 100 percent).

The chemical industry reduces the impact on the environment during synthesis,91870-15-4,2,5-Dichloro-1,8-naphthyridine,I believe this compound will play a more active role in future production and life.
