After stirring 2 h, the solution was cooled to room temperature, diluted with water, extracted with ethyl acetate and washed with saturated aq sodium chloride. The organic layer was dried over MgSO4, filtered and concentrated. Purification by column chromatography (10% ethyl acetate in heptane) provided 1-(3-bromo-benzyl)-7-trifluoromethyl-1,2,3,4-tetrahydro-quinoline 4.21 g (82%) as a colorless oil.
