Reaktionsschritte

A solution of 2,6,7-trichloro-3-pyridin-2-yl-quinoxaline (0.50 g) and N,N-dimethyl-ethane-1,2-diamine (0.28 g) in toluene (20 mL) was refluxed under nitrogen atmosphere for 16 hours. After refluxing, the reaction mixture was cooled, filtered, and concentrated under vacuum. The residue was purified by flash chromatography (silica gel, 1:9 methanol/dichloromethane) to give the product as a yellow solid (0.26 g); mp 95-97° C.
