Procedure
To a solution of (1R,3S,5R)-3-(3-chloro-2-fluoro-benzylcarbamoyl)-2-aza-bicyclo[3.1.0]hexane-2-carboxylic acid tert-butyl ester (6.35 g, 17.22 mmol) in CH2Cl2 (60 mL) was added TFA (13.18 mL, 172 mmol) and the solution was stirred at RT for 3 h. The crude reaction mixture was concentrated under vacuum, Et2O was added and the white precipitate was filtered off to give the desired compound as a TFA salt. MS (LC/MS): 287.0 [M+H]+, 285.1 [M−H]−; tR (HPLC conditions f) 1.27 min.
