Versuchsvorschrift

To a suspension of LAH (20 g, 0.526 mol) in dried THF (400 mL) was added dropwise a solution of (S)-methyl 5-oxo-1-((S)-1-phenylethyl)pyrrolidine-3-carboxylate (50 g, 0.202 mol) in dried THF (50 mL) at 0° C. The mixture was heated to reflux overnight. The reaction mixture was cooled to 0° C. and treated with water (20 mL) and aqueous NaOH (10%, 20 mL). The slurry formed was filtered off and washed with THF. The combined filtrate was evaporated to give compound ((S)-1-((S)-1-phenylethyl)pyrrolidin-3-yl)methanol, which was used directly in the next step.
