実験手順
To a solution of N-trifluoroacetyl-7-(2-Methyl-2H-pyrazol-3-yl)-1-methyl-2,3,4,5-tetrahydro-1H-3-benzazepine (30 mg, 0.082 mmol) in dichloromethane (1 mL) was treated with N-bromosuccinimide (15.3 mg, 0.086 mmol) and stirred overnight at 20 C. The product mixture was absorbed on silica and purified by flash chromatography (2-5% MeOH in CH2Cl2, silica) resulting in 37 mg of a white crystalline solid. MS calculated for C17H17BrF3N3O+H: 416, observed: 416.
