To a 50 mL round-bottomed flask was added 4-(4-cyclopropyl-1-methyl-1H-pyrazol-5-yl)-2-thiophenecarboxylic acid (105 mg, 0.42 mmol), 2-{(2S)-2-amino-3-[2-(trifluoromethyl)phenyl]propyl}-1H-isoindole-1,3(2H)-dione (152 mg, 0.39 mmol) [prepared according to Preparation 6] and PyBrop (246 mg, 0.52 mmol) in Chloroform (6 mL). DIEA (370 μL, 2.19 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 (171 mg, 66%): LC-MS (ES) m/z=579 (M+H)+.
