Procedure

To a stirred solution of [(3RS,4SR)-1-benzyl-4-(4-chloro-phenyl)-pyrrolidin-3-yl]-methyl-carbamic acid tert-butyl ester (1.30 g, 3.20 mmol) in toluene (30 ml) at RT, was added 1-chloroethyl chloroformate (0.53 ml, 4.80 mmol). The reaction mixture was stirred at 90° C. overnight and concentrated under vacuo. The residue was dissolved in MeOH (30 ml) and the reaction mixture was heated at 80° C. for 2 hours. The solvent was evaporated and the crude product was directly used in the next step without further purification.
