Participants

Reaction Steps

To a solution of 10.97 g (0.015 mole) of diethylamine in 20 ml of acetone 4.58 g (0.015 mole) of 1,2,3,4-tetrahydro-7-nitro-2,3-dioxo-6-quinoxalinesulfonyl chloride are added a temperature between 5° C. and 10° C., under stirring, the mixture is stirred at the same temperature for 3 hours and allowed to stand for 16 hours. Then 6 ml of acetic acid and 40 ml of water are added to the mixture, the separated crystals are filtered off, washed with water and acetone, dried and recrystallized from acetonitrile. Thus 3.50 g (59%) of N,N-diethyl-1,2,3,4-tetrahydro-7-nitro-2,3-dioxo-6-quinoxaline sulfonamide are obtained, m.p.: >360° C.
