Reaktionsschritte

Iodoethane (1.34 g) was added to a mixture of benzyl (S)-pyrrolidine-2-carboxylate (1.0 g) and potassium carbonate (1.77 g) in dry DMF (7 mL) and the resultant mixture was stirred at room temperature for 3 days. The mixture was diluted with water, extracted with ethyl acetate, washed with water, dried (MgSO4) and filtered. The filtrate was evaporated to dryness and the residue was purified by chromatography on silica, eluting with a mixture of ethyl acetate and pentane with a gradient of 10-20% to give benzyl (S)—N-ethylpyrrolidine-2-carboxylate (0.643 g) as a pale straw coloured oil.
