Reaction Steps
1 kg of 2,3 dichloroquinoxaline and 1 kg of 3-nitrobenzenesulfonamide are mixed in 5 volumes of acetonitrile. The reaction mixture is heated to reflux. 2.3 kg of DBU and 1 volume of acetonitrile are added. After completion of the reaction, cool down at 5° C. Add 12 volumes of methanol and 1.53 kg of HCl, filter the reaction mixture. Wash the cake with 6 volumes of methanol and dry under vacuum.
