Versuchsvorschrift

To a stirred solution of pyrrolidine (7.3 mL, 87 mmol) in dry tetrahydrofuran (5 mL), a solution of 3-bromomethyl-benzoic acid methyl ester (2.0 g, 8.7 mmol) in 5 mL of dry tetrahydrofuran was added dropwise and the mixture stirred at room temperature for 4 hours. The reaction mixture was then poured into 100 mL of saturated aqueous solution of sodium hydrogenocarbonate, extracted with 100 mL of ethyl acetate, dried over sodium sulfate and evaporated to dryness affording the title compound as yellow oil (1.85 g).
