실험 절차
A solution of N-trifluoroacetyl-1-isopropyl-7-methoxy-2,3,4,5-tetrahydro-1H-3-benzazepine (0.091 g, 0.29 mmol) in acetonitrile (3 mL) was treated with N-bromosuccinimide (0.057 g, 0.32 mmol), and stirred overnight at 20 C. After removing the solvent, flash chromatography (10% EtOAc in hexanes, silica) resulted in 0.056 g of a clear oil. MS calculated for C16H19BrF3NO2+H: 394, observed: 394.
