실험 절차

To a stirred suspension of dried Chloramine-T (5.10 g, 20.76 mmol) in CH3CN (100 mL) under a nitrogen atmosphere was added methylenecyclohexane (9.98 g, 104 mmol). Phenyltrimethylammonium tribromide (7.80 g, 20.76 mmol) was added in three portions over 10 min. The mixture was stirred at room temperature for 16 hours. The solvent was evaporated and the residue was partitioned between dichloromethane and water. The organic layer was dried over Na2SO4 and the solvent was evaporated. The residue was chromatographed on silica gel with an ISCO Combiflash using EtOAc/hexanes (5-30% gradient) to afford the title compound as a white solid (2.66 g).
