To a solution of 2-methoxycarbonylmethyltetrahydroquinoline (31.5 g, 0.153 mol) in DMF (750 mL) was added dropwise a solution of N-bromosuccinimide (27.41 g, 0.154 mol) in DMF (550 mL) at 0° C. The mixture was stirred for 2 h at the same temperature, poured into water (2 L), and extracted with a mixture of toluene and ethyl acetate. The organic layer was washed with water, dried over magnesium sulfate, and concentrated to give 44.72 g of the title compound (quant).
