To a solution of 3-bromonitrobenzene (2.02 g, 10 mmol) in toluene (33 mL) and pyrrolidine (1.0 mL, 12 mmol) was added sodium t-butoxide (1.92 g, 20 mmol) and the solution was deoxygenated by passing a nitrogen through the solution at room temperature for 15 minutes. BINAP and tris(dibenzylideneacetone)dipalladium(0) complex were subsequently added as a solid and the nitrogen bubbling was continued for an additional 5 minutes. The mixture was heated at 100° C. overnight. The reaction mixture was then cooled and partitioned between water and ethyl acetate. The organic layer was washed once with brine solution and dried over anhydrous sodium sulfate. The ethyl acetate was decanted and evaporated under reduced pressure to give the desired 1-(3-nitrophenyl)pyrrolidine as a red oil (1.5 g, 79%).
