With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.55687-02-0,6-Bromo-2-chloroquinoxaline,as a common compound, the synthetic route is as follows.
6-bromo-2-chloroquinoxaline (0.365 g 1.5 mmol) was dissolved in DMSO (10 mL) at room temperature and (R)-1-[3-(4-Methyl-piperazin-1-yl)-phenyl]-ethylamine (0.33 g, 1.5 mmol) and triethylamine (0.626 mL, 4.50mmol) were added to the solution. The reaction mixture was stirred at room temperature overnight. After completion of the reaction, water (100 mL) was added and the product was extracted with ethyl acetate (3 x 50 mL). The organic layer was washed with water (10 mL) followed by brine solution (10 mL) and dried over Na2SO4. The organic layer was concentrated in vacuo to afford the crude product.The product was purified by column chromatography using neutral silica gel of 60-120 mesh size and was eluted by a gradient of 5-15 % ethyl acetate in hexane to afford the title compound as a solid (0.250 g, 47%)., 55687-02-0
The synthetic route of 55687-02-0 has been constantly updated, and we look forward to future research findings.
