Procedure

To a round bottom flask containing 4-bromo-2-fluoro-1-nitro-benzene (640 mg, 2.92 mmol) was added 4-methyl piperidine (4 mL) and the reaction was stirred at 40° C. overnight. At this time the dark solution was poured into water (25 mL) and extracted with DCM (2×25 mL). The combined organic layers were washed with water (2×25 mL), dried (Na2SO4) and concentrated in vacuo to afford 556 mg (64%) of 1-(5-bromo-2-nitro-phenyl)-4-methyl-piperidine as an orange oil which was used without further purification.
