Reaction Steps
A mixture of 1-methyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (0.557 g, 2.68 mmol), bis(tri-t-butylphosphine)palladium (0.114 g, 0.223 mmol), 2-[(2S)-2-(5-bromo-1-oxo-1,3-dihydro-2H-isoindol-2-yl)-3-(3,5-difluorophenyl)propyl]-1H-isoindole-1, 3(2H)-dione (1.05 g, 2.06 mmol) and N,N-diisopropylethylamine (1.16 mL, 6.69 mmol) in 1,4-dioxane (12 mL, 150 mmol) and water (0.60 mL, 33 mmol) was stirred under microwave at 110° C. for 15 minutes. The reaction mixture was filtered through a pad of celite and the filtrate was concentrated under reduced pressure. The residue was purified by combi-flash chromatography eluted with EtOAc/hexane (30-100%) to give 0.72 g (68.4% yield) of the desired product. LCMS found: 513.1 (M+H)+.
