Procedure

4-(4-Chlorocarbonylbenzyl)-nitrobenzene was dissolved in dichloromethane (40 mL) and a solution of pyrrolidine (64 mg, 1 eq) in pyridine (0.2 mL) was added. The mixture was stirred for 2 hours at room temperature, washed with dilute potassium hydroxide, and solvents evaporated to yield a yellow oil. The residue was chromatographed on silica gel, eluting with dichloromethane/methanol, to give 4-(4-pyrrolidin-1-ylcarbonylbenzyl)-nitrobenzene (299 mg, 99%).
