Reaction Steps

A −20° C. mixture of DIEA (552 mg, 4.27 mmol) and pyrrolidine (152 mg, 2.137 mmol) in THF (5 mL) was treated drop-wise with a solution of 2-(bromomethyl)-1-fluoro-4-nitrobenzene (500 mg, 2.137 mmol) in THF (5 mL), allowed to warm to RT and stirred for 6 h. The mixture was treated with EtOAc, washed with water, then brine, dried over Na2SO4 and concentrated to dryness to afford 1-(2-fluoro-5-nitrobenzyl)pyrrolidine (450 mg, 94% yield). MS (ESI) m/z: 225.1 [M+H]+.
