Procedure

To a 50 mL round-bottomed flask was added 4-(3-chloro-1,4-dimethyl-1H-pyrazol-5-yl)-2-thiophenecarboxylic acid (238 mg, 0.93 mmol) [prepared according to the procedure of Example 176], 2-{(2S)-2-amino-3-[3-(trifluoromethyl)phenyl]propyl}-1H-isoindole-1,3(2H)-dione (355 mg, 0.92 mmol) [prepared according to the procedure of Preparation 6, except substituting N-{[(1,1-dimethylethyl)oxy]carbonyl}-3-(trifluoromethyl)-L-phenylalanine (5.0 g, 15.0 mmol) for N-{[(1,1-dimethylethyl)oxy]carbonyl}-2-(trifluoromethyl)-L-phenylalanine] and PyBrop (532 mg, 1.13 mmol) in chloroform (9.5 mL). DIEA (820 μL, 4.70 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 (448 mg, 0.72 mmol, 78%): LC-MS (ES) m/z=587 (M+H)+.
