Reaktionsschritte
To a solution of (2RS)-2-benzyl-pyrrolidine-1-carboxylic acid tert-butyl ester (1.21 g, 4.6 mmol) in ethyl acetate (20 ml) was added hydrogen chloride (4N) in ethyl acetate (20 ml) at room temperature. The mixture was stirred at room temperature for 2 hours and was concentrated. The residue was partitioned between aqueous sodium hydrogen carbonate and chloroform, and the organic layer was dried over sodium sulfate. The solvent was evaporated under reduced pressure to afford (2RS)-2-benzyl-pyrrolidine (0.7 g, 93%).
