Reaction Steps
To a mixture of N-methyl-(5-trifluoromethyl-pyridin-2-yl)-amine (3.48 g) and DMF (20 ml), N-bromosuccinimide (4.27 g) was added, and stirred at room temperature for 1 hour. Into the reaction mixture, saturated aqueous ammonium chloride solution was poured, and extracted with ethyl acetate. The organic layer was dried over sodium sulfate, and concentrated under reduced pressure. The resulting residue was subjected to silica gel column chromatography to give 4.8 g of N-methyl-(3-bromo-5-trifluoromethyl-pyridin-2-yl)-amine.
