Reaction Steps

A solution of (S)-N-Trifluoroacetyl-8-chloro-1-methyl-2,3,4,5-tetrahydro-1H-3-benzazepine (0.875 g, 3.0 mmol) in dichloroethane (7 mL) was treated with N-bromosuccinimide (0.284 g, 2.1 mmol) and trifluoromethansulfonic acid (0.639 g, 4.2 mmol). The reaction was stirred for 16 h at 75° C., diluted with ethyl acetate (20 mL) and extracted with water (2×10 mL). The organics were dried with MgSO4, filtered and concentrated. Flash chromatography (5% EtOAc in hexanes, silica) resulted in 0.13 g of a clear oil. MS calculated for C13H12BrClF3NO+H: 370, observed: 370.
