Procedure

To a solution of 5-chloro-4-(4-chloro-1-ethyl-1H-pyrazol-5-yl)-2-thiophenecarboxylic acid (180 mg, 0.618 mmol) [from Example 235(c)] in DCM (5 mL) at 25° C. was added PyBrOP in one portion, followed by addition of DIPEA (0.54 mL, 3.09 mmol). After stirring for 10 min, 2-[(2S)-2-amino-3-(3-fluorophenyl)propyl]-1H-isoindole-1,3(2H)-dione (203 mg, 0.68 mmol) was added to above solution in one portion. After stirring for 2 h, the solution was concentrated and purified via column chromatography (silica, 20-50% EtOAc/Hexane) affording the title compound (285 mg, 77%) as a white solid: LC-MS (ES) m/z=571 (M+H)+.
