Procedure

To a 50 mL round-bottomed flask was added 4-(1-methyl-1H-pyrazol-5-yl)-2-thiophenecarboxylic acid (160 mg, 0.62 mmol) [prepared according to the procedure of Example 146], 2-[(2S)-2-amino-3-(2,6-difluorophenyl)propyl]-1H-isoindole-1,3(2H)-dione (231 mg, 0.69 mmol) [prepared according to the procedure of Preparation 18] and PyBrop (353 mg, 0.75 mmol) in chloroform (8 mL). DIEA (0.64 mL, 3.66 mmol) was added and the mixture stirred overnight at room temperature. The reaction mixture was adsorbed onto silica and purified via column chromatography (25-75% EtOAc/Hex) affording the title compound (149 mg, 0.21 mmol, 30%): LC-MS (ES) m/z=507 (M+H)+
