실험 절차

A solution of N-trifluoroacetyl-7-methoxy-1-methyl-2,3,4,5-tetrahydro-1H-3-benzazepine (1.25 g, 4.35 mmol) in acetonitrile (40 mL) was treated with N-bromosuccinimide (0.852 g, 4.79 mmol) and stirred overnight at 20 C. The product mixture was diluted with EtOAc (200 mL), washed with saturated aqueous sodium bisulfite (100 mL) and brine (100 mL), dried with Na2SO4 and concentrated. Flash chromatography (15% EtOAc in hexane, silica) resulted in 1.55 g of a clear oil. 1H NMR (400 MHz, CDCl3, mixture of rotamers) d 7.34 (s, 1 H), 6.65 (m, 1 H), 3.87 (s, 3H), 3.81 (m, 1 H), 3.55 (m, 1.3 H), 3.37 (m, 0.7 H), 3.2-2.9 (bm, 4 H), 1.30 (m, 3 H). MS calculated for C14H15BrF3NO2+H: 366, observed: 366.
