Procedure

To a solution of 5-bromo-3-furancarboxylic acid (0.30 g, 1.57 mmol) [prepared according to J. Org. Chem. 1976, 41, 2350.], 2-{(2S)-2-amino-3-[2-(trifluoromethyl)phenyl]propyl}-1H-isoindole-1,3(2H)-dione (0.60 g, 1.73 mmol) [from Preparation 5] and diisopropylethyl amine (0.82 mL, 4.7 mmol) in DCM (50 mL) at 25° C. was added PyBrOP (1.09 g, 2.36 mmol) in one portion. After 16 h, the solution was partitioned between H2O and washed with DCM. The combined organic fractions were dried (Na2SO4), concentrated and purified via column chromatography (silica, hexanes/EtOAc, 1:1) affording the title compound (0.45 g, 55%) as a white solid: LC-MS (ES) m/z=521 (WH)+.
