Bromine → N-(3,5-Bis-trifluoromethyl-benzyl)-N-(9-bromo-7-trifluoromethyl-2,3,4,5-tetrahydro-1H-benzo[b]azepin-5-yl)-acetamide

Participants

Reaction Steps

To a solution of crude N-(3,5-Bis-trifluoromethyl-benzyl)-N-(7-trifluoromethyl-2,3,4,5-tetrahydro-1H-benzo[b]azepin-5-yl)-acetamide (0.0980 mg, 0.197 mmol) in HOAc (2.00 ml), was added bromine (0.0106 ml, 0.207 mmol) dropwise. The reaction mixture was stirred at room temperature overnight. Remove the solvent on a rotary evaporator. Purification by silica gel chromatography (eluent, 0-40% ethyl acetate in hexane) provided the titled compound (0.0850 mg, 75%). MS (ES+): 577, 579 (M+H).
