Procedure

Dissolve 2-(R)-(2-(S)-dibenzylamino-1-(S)-hydroxy-3-phenylpropyl)-pyrrolidine-1-carboxylic acid tert-butyl ester (0.75 g, 1.49 mmol) in methanol (20 mL). Add 20% palladium hydroxide on carbon (0.33 g) and stir 1 h under one atmosphere of hydrogen gas. Filter through filter agent and concentrate to give the title compound as a white foam (0.45 g, 93%).
