Versuchsvorschrift

2-(2-Chlorophenoxy)ethanol (0.229 g, 1.33 mmol) was treated with NaH (55% dispersion in mineral oil; 0.058 g, 1.33 mmol) in dioxane (2 mL). After stirring at room temperature for 3 h, the mixture was added dropwise to a slurry of 2.3-dichloroquinoxaline (0 320 g, 1.60 mmol) in dioxane (1 mL). The resulting mixture was stirred at room temperature for 15 h to produce the intermediate 2-chloro-3-[2-(2-chlorophenoxy)ethoxy]quinoxaline which was used directly in the next step.
