Reaction Conditions:

with thionyl chloride;N,N-dimethyl-formamide for 1 h;Reflux;

Steps:

General procedure for the chlorination of dihydroxyquinoxalines in 1-chlorobutane

General procedure: N,N-Dimethylformamide (0.5 mg, 0.0673 mmol) was added dropwise to a slurry of 2,3-dihydroxyquinoxaline (2.0 g,12.3 mmol) and thionyl chloride (2.92 g, 24.6 mmol) in1-chlorobutane (20 mL). The mixture was refluxed for 1h.Then cooled to ambient temperature, the obtained needles were filtered, washed with ethyl ether, and dried.
