To a suspension of 1-(3-trifluoromethyl-pyridin-2-yl)-piperazine (230 mg, 1 mmol, Oakwood Products) in dichloromethane (5 mL) was added a solution of bromine in dichloromethane (1.5 mL, 1 M, 1.5 mmol). The reaction mixture was stirred at 25° C. for 2 h. The precipitated yellow solid was filtered, washed with small amount of methanol and dried in vacuo to give the title compound as a yellow amorphous solid. MS (ESI, pos. ion) m/z: 311 (M+1).
