Procedure

EDC (0.0469 g, 0.24 mmol was added to a stirred mixture of N-(5-chloro-2-{2,2-difluoro-1-[(4-methoxyphenyl)amino]ethyl}benzyl)-L-prolinamide (0.0691 g, 0.16 mmol), (R)-hexahydromandelic acid (0.0258 g, 0.16 mmol) and HOAT (0.0111 g, 0.08 mmol) in DMF (2.0 mL). After 2 h the mixture was partitioned between EtOAc and water. The organic layer was washed with brine, dried (Na2SO4) and evaporated in vacuo and the residue was purified by flash column chromatography on silica (eluting with 5% methylene chloride, 10-70% ethyl acetate/hexanes gradient) to give N-(5-chloro-2-{2,2-difluoro-1-[(4-methoxyphenyl)amino]ethyl}benzyl)-1-[(2R)-2-cyclohexyl-2-hydroxyethanoyl]-L-prolinamide (0.0332 g) as a white solid; LC-MS m/z=564.4.
