To a 50 mL round-bottomed flask was added 5-methyl-4-(1-methyl-1H-pyrazol-5-yl)-2-thiophenecarboxylic acid (206 mg, 0.93 mmol) [prepared according to the procedure of Preparation 9], 2-{(2S)-2-amino-3-[2-(trifluoromethyl)phenyl]propyl}-1H-isoindole-1,3(2H)-dione (209 mg, 0.60 mmol) [prepared according to the procedure of Preparation 6] and PyBrop (340 mg, 0.73 mmol) in Chloroform (15 mL). DIEA (0.81 mL, 4.65 mmol) was added and the mixture stirred overnight at room temperature. Upon completion, the reaction mixture was adsorbed onto silica and purified via column chromatography (25-75% EtOAc/Hex) affording the title compound (112 mg, 0.203 mmol, 22%): LC-MS (ES) m/z=553 (M+H)+
