Procedure

To a solution of 5-chloro-4-(1-methyl-1H-pyrazol-5-yl)-2-thiophenecarboxylic acid (0.21 g, 0.87 mmol), PyBrOP (610 mg, 1.3 mmol) and diisopropylethyl amine (0.76 mL, 4.35 mmol) in DCM (20 mL) at 25° C. was added 2-[(2S)-2-amino-3-phenylpropyl]-1H-isoindole-1,3(2H)-dione HCl (380 mg, 0.96 mmol)[prepared according to Preparation 5]. 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 (200 mg, 46%) as a white solid: LC-MS (ES) m/z=505 (M+H)+.
