反应详情

In THF (250 ml) was dissolved 4-nitrobenzyl bromide (25.0 g), and to the mixture was added pyrrolidine (24.1 ml) at 0° C. The reaction mixture was stirred at room temperature for 60 hours. To the mixture was added water (500 ml), and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated sodium chloride solution, dried with anhydrous sodium sulfate, and concentrated under reduced pressure. The residue was separated and purified with column chromatography (ethyl acetate) to give 1-(4-nitrobenzyl)pyrrolidine (23.5 g) as orange oil.
