실험 절차

To a solution of 5-cyano-2-(3,5-dichloro-phenoxy)-N-(2-dimethylamino-ethyl)-benzene-sulfonamide (41.4 mg, 0.1 mmol) in dry DMF (2 ml) was added 1-(2-bromo-ethyl)-pyrrolidine-2,5-dione (30.9 mg, 0.15 mmol) and NaH (60%, 6.00 mg, 0.15 mmol). The mixture was stirred for 8 hours at 90° C. After cooled to room temperature, the solvent was evaporated. The mixture was diluted with EtOAc (60 ml), washed with brine, and dried over MgSO4. The solvent was evaporated and the residue was purified by preparative TLC (CH2Cl2/CH3OH=20/1) to give 5-cyano-2-(3,5-dichloro-phenoxy)-N-(2-dimethylamino-ethyl)-N-[2-(2,5-dioxo-pyrrolidin-1-yl)-ethyl]-benzenesulfonamide (44 mg, 81.6%) and the free base was converted into HCl salt by 4N HCl in dioxane.
