실험 절차
(Step 2) To a suspension of 2-cyano-2-(3,4-dichloro-5-oxo-2,5-dihydrofuran-2-yl)acetamide (0.28 g) and 3-(aminomethyl)-N-methylbenzenesulfonamide obtained in Step 1 (0.36 g) in ethanol (10 ml) was added potassium carbonate (0.25 g) at room temperature, and the mixture was stirred overnight at 70° C. The reaction solution was filtered through celite. The solvent was evaporated under reduced pressure. The residue was purified by basic silica gel column chromatography (ethyl acetate:hexane=7:3→1:0). 4N Hydrochloride-ethyl acetate solution (1 ml) was added to the obtained yellow oil, and the precipitated crystals were collected by filtration, and recrystallized to give the title compound (76 mg).
