Participants

Reaction Steps

To a suspension of 2,3-dichloroquinoxaline (33.5 g; 0.168 mole) in 500 ml ethanol, hydrazine hydrate (18.5 g; 0.37 mole) was added and the reaction mixture was stirred vigorously at room temperature for 16 hours. The thick slurry was filtered, washed with ethanol to give 23.7 g of 2-chloro-3-hydrazinoquinoxaline having a mp of 181°-182° C. (dec.).
