Reaction Steps

To a solution of 2-aminocyclopent-1-enecarbonitrile (440 mg, 4.07 mmol) in 10 mL of DMA was added sulfamoyl chloride (941.3 mg, 8.15 mmol), and the resultant mixture was stirred at room temperature under nitrogen for 2 h. Then it was diluted with EtOAc, the organic layer was washed with brine and dried down under vacuum, and the residue was purified by chromatography on silica gel eluting with EtOAc/Hexane to give the title compound. 1H NMR (400 MHz, CDCl3) δ 2.04-1.97 (m, 2H), 2.61-2.57 (m, 2H), 2.9-2.86 (m, 2H), 5.66 (s, 2H), 8.04 (s, 1H).
