실험 절차

To a solution of 4-(1-methyl-1H-pyrazol-5-yl)-2-furancarboxylic acid (54 mg, 0.28 mmol), 2-{(2S)-2-amino-3-[2-(trifluoromethyl)phenyl]propyl}-1H-isoindole-1,3(2H)-dione (108 mg, 0.28 mmol) [prepared in Preparation 6] and N,N-diisopropylethylamine (0.24 ml, 1.40 mmol) in DCM at 25° C. was added bromo-tris-pyrrolidino-phosphonium hexafluorophosphate (158 mg, 0.34 mmol) in one portion. The solution stirred at 25° C. for 1 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, 50% EtOAc in hexanes) yielding N-((1S)-2-(1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl)-1-{[2-(trifluoromethyl)phenyl]methyl}ethyl)-4-(1-methyl-1H-pyrazol-5-yl)-2-furancarboxamide (100 mg, 0.14 mmol, 50% yield) as a white solid: LCMS (ES) m/e 523 (M+H)+.
