Procedure

TFA (2.50 mL) was added to a stirred solution of N-(5-chloro-2-{2,2-difluoro-1[(4-methoxyphenyl)amino]ethyl}benzyl)-1-(tert-butoxycarbonyl)-L-prolinamide (0.256 g, 0.49 mmol) in CH2Cl2 (5.0 mL). After 1 h the solvent was evaporated in vacuo and the residue was partitioned between EtOAc and saturated aqueous Na2CO3. The organic layer was dried (Na2SO4) and evaporated in vacuo to give the N-(5-Chloro-2-{2,2-difluoro-1-[(4-methoxyphenyl)amino]ethyl}benzyl)-L-prolinamide (0.207 g) as a gum.
