Reaction Steps

To a solution of 4-(4-bromo-1-methyl-1H-pyrazol-5-yl)-5-propyl-2-thiophenecarboxylic acid (171 mg, 0.52 mmol), 2-{(2S)-2-amino-3-[2-(trifluoromethyl)phenyl]propyl}-1H-isoindole-1,3(2H)-dione (200 mg, 0.52 mmol)[prepared according to Preparation 6] and diisopropylethylamine (0.45 ml, 2.60 mmol) in DCM at 25° C. was added bromo-tris-pyrrolidino-phosphonium hexafluorophosphate (267 mg, 0.57 mmol) in one portion. The solution stirred at 25° C. for 12 h and was then dry loaded onto silica and purified via column chromatography (silica, 30-70% EtOAc in hexanes) yielding 4-(4-bromo-1-methyl-1H-pyrazol-5-yl)-N-((1S)-2-(1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl)-1-{[2-(trifluoromethyl)phenyl]methyl}ethyl)-5-propyl-2-thiophenecarboxamide (251 mg, 0.37 mmol, 72% yield) as a yellow oil: LCMS (ES) m/e 659,661 (M, M+2)+.
