To a stirred solution of 4-[(3RS,4SR)-3-[(SR)-1-(5-cyano-pyridin-2-yloxy)-ethyl]-4-(3,4-dichloro-phenyl)-pyrrolidine-1-carbonyl]-piperidine-1-carboxylic acid tert-butyl ester (0.28 g, 0.50 mmol) in 24 mL of CH2Cl2 was added 6 mL of TFA. After one hour at RT, the reaction was quenched by addition of aq. NaOH 1M (until ph=10) and the product was extracted with CH2Cl2. The combined organic phases were dried over Na2SO4 and concentrated under vacuo to yield 0.237 g (99%) of the title compound as a white foam. ES-MS m/e: 473.0 (M+H+). Pyrrolidine VIII-B-2
