Procedure

To a solution of (3S)-8,8-difluoro-2-{N-[(methyloxy)carbonyl]-L-valyl}-2-azaspiro[4.5]decane-3-carboxylic acid (116) (168 mg, 0.45 mmol) and 2-[4′-(bromoacetyl)-4-biphenylyl]-2-oxoethyl N-[(methyloxy)carbonyl]-L-valyl-L-prolinate (70) (250 mg, 0.43 mmol) in anhydrous acetonitrile (2 mL) was added triethylamine (0.09 mL, 0.64 mmol) and the reaction stirred at room temperature under nitrogen for 1 h. The reaction was partitioned between EtOAc and 0.1 N HCl (30 mL each), the organic layer was washed with brine and dried (MgSO4) and concentrated in vacuo. The residue was purified by silica gel chromatography eluting with 65-100% hexanes/EtOAc to afford the title compound as an off white solid (309 mg, 82% yield).
