Procedure

To a solution of 5-(1-methyl-1H-pyrazol-5-yl)-2-thiophenecarboxylic acid (100 mg, 0.48 mmol), PyBrOP (270 mg, 0.58 mmol) and diisopropylethyl amine (420 μL, 2.4 mmol) in DCM (5 mL) at 25° C. was added 2-{(2S)-2-amino-3-[2-(trifluoromethyl)phenyl]propyl}-1H-isoindole-1,3(2H)-dione-HCl (168 mg, 0.48 mmol) [from Preparation 6]. After 16 h, the solution was partitioned between H2O and washed with DCM. The combined organic fractions were dried (Na2SO4), concentrated and purified via column chromatography (silica) affording the title compound (74 mg, 28%) as a white solid: LC-MS (ES) m/z=539 (M+H)+.
