Reaction Steps

Pyrrolidine (21.6 g, 304.23 mmol), L-proline (1.12 g, 9.74 mmol), and CuI (960 mg, 5.05 mmol) were added sequentially to 1-iodobenzene (10.0 g, 49.02 mmol). DMSO (40 mL) was then added, and the resulting solution was stirred at 60° C. for 20 hours. The reaction mixture was then quenched by adding 400 mL of iced water. The resulting solution was extracted with ethyl acetate (3×150 mL), and the organic layers were combined, dried (Na2SO4), filtered and concentrated. The residue was purified by column chromatography using a 1:100 ethyl acetate/petroleum ether solvent system to afford 4.3 g (57%) of 1-phenylpyrrolidine as brown oil.
