Participants

Reaction Steps

A mixture of 4.58 g (0.015 mole) of 1,2,3,4-tetrahydro-7-nitro-2,3-dioxo-6-quinoxalinesulfonyl chloride and 30 ml of 25% ethanolic dimethylamine is stirred at a temperature between 5° C. and 10° C. for 3 hours, and then allowed to stand for 16 hours. To the reaction mixture 5 ml of acetic acid and 60 ml of water are added, the separated crystals are filtered, washed with water and acetone, dried, dissolved in a slight amount of hot dimethyl sulfoxide and precipitated from this solution with water. Thus 3.80 g (81%) of N,N-dimethyl-1,2,3,4-tetrahydro-7-nitro-2,3-dioxo-6-quinoxaline sulfonamide are obtained, m.p.: 318-332° C.
