实验步骤: A solution of cis-2,6-dimethylpiperazine (5.0 g) and sulfamide (10.0 g) in 1,4-dioxane (100 ml) was stirred for 72 h at 110° C. The volatiles were removed in vacuo and the residue suspended in EtOAc. The filtrate was evaporated to a yellow solid (4.3 g). 1 g of this material was dissolved in methanol and applied to an SCX cartridge (10 g). The cartridge was washed with 50% aqueous methanol (200 ml) before the subtitle product was eluted with 5% ammonium hydroxide solution/methanol (200 ml). The solvent was removed under reduced pressure to yield the subtitle compound as a yellow solid. Yield: 0.46 g.
