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, 4.50 mmol) 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 (3×50 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.
