2,3-Dichloro-6-methylquinoxaline Use and Manufacturing
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.
