The above 6,7-dichloro-3-[2-(4-fluorophenyl)vinyl]-1H-quinoxalin-2-one (2.0 g, 6 mmol), 4-dimethylaminopyridine (0.2 g) and phosphorous oxychloride (POCl3) were mixed and refluxed for 30 minutes. After cooling, the mixture was poured onto ice (500 ml). The solid was filtered, washed with water and dried in vacuo at 30° C. overnight to afford 1.8 g (83%) of the title compound.
