2213-63-0, 2,3-Dichloroquinoxaline is a quinoxaline compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
REFERENCE EXAMPLE 7-12-amino-3-[(pyridin-3-yl)methoxy]quinoxaline (Compound BA)Step 1; 2,3-Dichloroquinoxaline (9.90 g, 50.0 mmol) and ammonium carbonate (24.3 g, 300 mmol) were suspended in N,N-dimethylformamide (50 mL) in a stainless steel sealed tube and the mixture was stirred at 60 C. for 72 hours. After water was added to the reaction mixture, extraction with ethyl acetate was performed, followed by washing with brine and drying over anhydrous sodium sulfate. The solvent was evaporated off under reduced pressure, and the residue was purified by silica gel column chromatography (hexane/ethyl acetate=7/3). Further, slurry purification was performed using diisopropyl ether, to give 2-amino-3-chloroquinoxaline (2.41 g, yield: 270).ESIMS m/z: 180 (M+H)+; 1H-NMR (270 MHz, CDCl3, delta): 5.37 (br s, 2H), 7.43-7.50 (m, 1H), 7.59-7.70 (m, 2H), 7.84-7.87 (m, 1H).
The synthetic route of 2213-63-0 has been constantly updated, and we look forward to future research findings.
