Procedure

To a solution of methyl 4-methyl-5-(1-methyl-1H-pyrazol-5-yl)-2-thiophenecarboxylate (217 mg, 0.918 mmol), 2-{(2S)-2-amino-3-[2-(trifluoromethyl)phenyl]propyl}-1H-isoindole-1,3(2H)-dione (353 mg, 0.92 mmol)[prepared according to Preparation 6] and diisopropylethylamine (0.800 ml, 4.59 mmol) in DCM at 25° C. was added bromo-tris-pyrrolidino-phosphonium hexafluorophosphate (472 mg, 1.01 mmol) in one portion. The solution stirred at 25° C. for 12 h and was then 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, 30-70% EtOAc in hexanes) yielding 4-(1,4-dimethyl-1H-pyrazol-5-yl)-N-((1S)-2-(1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl)-1-{[2-(trifluoromethyl)phenyl]methyl}ethyl)-5-methyl-2-thiophenecarboxamide (373 mg, 0.66 mmol, 71.7% yield) as a yellow foam: LCMS (ES) m/e 567 (M+H)+.
