Procedure

To a 50 mL round-bottomed flask was added 5-methyl-4-(1-methyl-1H-pyrazol-5-yl)-2-thiophenecarboxylic acid (200 mg, 0.90 mmol) [Prepared according to the procedure of Example 151], 2-[(2S)-2-amino-3-(3-fluorophenyl)propyl]-1H-isoindole-1,3(2H)-dione (291 mg, 0.87 mmol) [Prepared according to the procedure of preparation 6 except substituting N-{[(1,1-dimethylethyl)oxy]carbonyl}-3-fluoro-L-phenylalanine (5.03 g, 17.8 mmol) for N-{[(1,1-dimethylethyl)oxy]carbonyl}-2-(trifluoromethyl)-L-phenylalanine] and PyBrop (512 mg, 1.09 mmol) in Chloroform (9 mL). DIEA (790 μL, 4.52 mmol) was added and the mixture stirred overnight at room temperature. The mixture was adsorbed onto silica and purified via column chromatography (25-70% EtOAc/Hex) affording the title compound (250 mg, 50%): LC-MS (ES) m/z=503 (M+H)+.
