Reaction Steps

4-(3-Amino-propyl)-piperazin-2-one (3.45 g) and triethylamine (5.18 mL, 3.76 g) were added to 1,4-dioxane (100 mL) and N,N-dimethylacetamide (20 mL) and mixed until dissolved. 4-Chloro-3-nitrobenzenesulfonamide (4.00 g) was added, and the mixture was heated to 90° C. for 16 hours. The mixture was cooled and the solvent was removed under vacuum. The material purified by recrystallization from 20% methanol in dichloromethane with subsequent washing of the recrystallized solid with 10% methanol in dichloromethane followed by washing with 100% dichloromethane.
