Name is 1,5-Naphthyridin-2(1H)-one, as a common heterocyclic compound, it belongs to naphthyridine compound, and cas is 10261-82-2, its synthesis route is as follows.,10261-82-2
0001-2 Phosphorus oxychloride (8.3 mL) was added to 1,5-naphthyridin-2-ol (2.76 g), followed by stirring at 100 C. for 5 hours. The reaction mixture was cooled to room temperature, and added dropwise to a mixture of ethyl acetate (30 mL), water (30 mL), and sodium carbonate (9.57 g) over a period of 1 hour in an ice bath. Water (10 mL) was added thereto, and sodium carbonate was added thereto, followed by adjusting the pH of the resultant product to 8.3. The resultant product was stirred at room temperature for 10 minutes, and ethyl acetate (270 mL) and water (200 mL) were added thereto. The organic layer was collected by separation, and the aqueous layer was extracted two times with ethyl acetate (200 mL). The organic layer and the extraction liquid were combined, the resultant product was dried over anhydrous sodium sulfate, and the solvent was distilled off under reduced pressure, thereby obtaining 2-chloro-1,5-naphthyridine (2.86 g) as a pale yellow solid. MS m/z (M+H): 165.
With the complex challenges of chemical substances, we look forward to future research findings about 1,5-Naphthyridin-2(1H)-one
