Procedure

To a solution of 4-chloro-5-(4-chloro-1-methyl-1H-pyrazol-5-yl)-2-thiophenecarboxylic acid (136.1 mg, 0.49 mmol), 2-{(2S)-2-amino-3-[2-(trifluoromethyl)phenyl]propyl}-1H-isoindole-1,3(2H)-dione (179 mg, 0.51 mmol)[prepared according to Preparation 6], diisopropylethyl amine (260 uL, 1.5 mmol) in DCM (5 mL) was added PyBrop (341 mg, 0.75 mmol) in one portion. After 1 h, the reaction contents were partitioned between H2O/DCM. The aqueous phase was washed several times with DCM and the combined organic fractions were dried over Na2SO4, concentrated and purified via column chromatography (silica, gradient 0-50% ethyl acetate/hexane) affording the title compound (242 mg, 82%) as a white solid: LCMS (ES) m/z=607 (M+H)+.
