Hydrochloric Acid → 3-(4-Fluorophenoxy)pyrrolidine

Participants

Reaction Steps

4N hydrogen chloride in dioxane (200 ml) is added to a solution of 3-(4-fluoro-phenoxy)-pyrrolidine-1-carboxylic acid tert-butyl ester 5 (39.43 g, 140 mmol) in ethanol (200 ml) and the mixture stirred at room temperature for 18 hours. The solvent is evaporated under vacuum and the residue basified using 4N sodium hydroxide solution (200 ml). The resulting product is extracted using DCM (3×100 ml). The organic extracts are dried (using MgSO4), filtered and evaporated to give the title compound as a light brown oil.
