Procedure

To a 50 mL round-bottomed flask was added 5-chloro-4-(4-chloro-1-methyl-1H-pyrazol-5-yl)-2-thiophenecarboxylic acid (320 mg, 1.16 mmol) [prepared according to the procedure of Example 168], 2-[(2S)-2-amino-3-(4-fluorophenyl)propyl]-1H-isoindole-1,3(2H)-dione (318 mg, 0.95 mmol) [prepared according to the procedure of Preparation 6 except substituting N-{[(1,1-dimethylethyl)oxy]carbonyl}-4-fluoro-L-phenylalanine (4.95 g, 17.5 mmol) for N-{[(1,1-dimethylethyl)oxy]carbonyl}-2-(trifluoromethyl)-L-phenylalanine] and PyBrop (535 mg, 1.14 mmol) in Chloroform (9.5 mL). DIEA (840 μl, 4.81 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 (106 mg, 0.16 mmol, 17%): LC-MS (ES) m/z=557 (M+H)+.
