실험 절차

Prepare a solution with 0.585 kg of 2-chloro-5-methoxyaniline-HCl, 3.5 volumes of acetonitrile and 0.46 kg of DBU. (solution A) Mix 1 kg of N-(3-chloroquinoxalin-2-yl)-3-nitrobenzenesulfonamide and 5.5 volumes of acetonitrile. Heat to reflux. Add solution A and 1 volume of acetonitrile onto the reaction mixture. After completion of the reaction at reflux, cool down at 20° C., dilute with 10 volumes of methanol and filter. Wash the cake 3 times with 5 volumes of methanol and dry it under vacuum.
