Versuchsvorschrift
A solution of N-trifluoroacetyl-1-ethyl-7-methoxy-2,3,4,5-tetrahydro-1H-3-benzazepine (0.600 g, 1.99 mmol) in acetonitrile (20 mL) was treated with N-chlorosuccinimide (0.057 g, 0.32 mmol), and stirred overnight at 60 C. The product mixture was concentrated, diluted with EtOAc (100 mL), washed with water (50 mL) and brine (50 mL), dried with Na2SO4 and concentrated. Flash chromatography (10% EtOAc in hexanes, silica) resulted in 0.421 g of a clear oil. MS calculated for C15H17ClF3NO2+H: 336, observed: 336.
