Procedure

To a 50 mL round-bottomed flask was added 4-(4-chloro-1-methyl-1H-pyrazol-5-yl)-5-(methyloxy)-2-thiophenecarboxylic acid (208 mg, 0.76 mmol) [prepared according to the procedure of Example 188], 2-[(2S)-2-amino-3-(4-fluorophenyl)propyl]-1H-isoindole-1,3(2H)-dione (257 mg, 0.77 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 (435 mg, 0.93 mmol) in chloroform (7.6 mL). DIEA (670 μL, 3.84 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 (238 mg, 0.43 mmol, 56%): LC-MS (ES) m/z=553 (M+H)+.
