Participants

Reaction Steps

To the crude 4-(1-ethyl-4-methyl-1H-pyrazol-5-yl)-2-furancarboxylic acid in DCM (5 mL) at 25° C. was added PyBrOP (370 mg, 0.79 mmol) in one portion, followed by the addition of DIPEA (0.8 mL, 4.58 mmol). After 10 min, 2-[(2S)-2-amino-3-(3-fluorophenyl)propyl]-1H-isoindole-1,3(2H)-dione (220 mg, 0.74 mmol) was added to the reaction solution. After 2 h, the reaction mixture was concentrated and purified via column chromatography (silica, 20-50% EtOAc/Hexane) affording the title compound (164 mg, 54%) as a white solid: LC-MS (ES) m/z 501 (M+H)+.
