Procedure

To a 50 mL round-bottomed flask was added 5-chloro-4-(4-chloro-1-methyl-1H-pyrazol-5-yl)-2-thiophenecarboxylic acid (235 mg, 0.85 mmol) [prepared according to the procedure of Example 96], 2-[(2S)-2-amino-3-(2,5-difluorophenyl)propyl]-1H-isoindole-1,3(2H)-dione (290 mg, 0.82 mmol) [prepared according to the procedure of Preparation 18 except substituting 2,5-difluoro-L-phenylalanine (3.02 g, 15.0 mmol) for 2,6-difluoro-L-phenylalanine] and PyBrop (479 mg, 1.02 mmol) in chloroform (8.5 mL). DIEA (742 μL, 4.25 mmol) was added and the reaction stirred overnight at room temperature. The mixture was adsorbed onto silica and purified via column chromatography (25-70% EtOAc/Hex) affording the title compound (174 mg, 0.30 mmol, 36%): LC-MS (ES) m/z=575 (M+H)+.
