Procedure

2-[2-(4-bromo-1H-pyrazol-1-yl)ethyl]-1H-isoindole-1,3(2H)-dione (for a preparation see Intermediate 28) (80 mg, 0.250 mmol) and 1-methylethyl[1-acetyl-2-methyl-6-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1,2,3,4-tetrahydro-4-quinolinyl]carbamate (Intermediate 12, 150 mg, 0.360 mmol) were mixed with potassium carbonate (69.1 mg, 0.500 mmol) and tetrakis(triphenylphosphine)palladium(0) (14.44 mg, 0.012 mmol), dissolved in ethanol (1 mL) and toluene (1 mL) and stirred under nitrogen at 90° C. for 1 hour. The mixture was partitioned between distilled water (20 mL) and EtOAc (60 mL). The aqueous layer was extracted with EtOAc (60 mL) and the organic fractions were combined, washed (brine, 30 mL), dried (MgSO4), filtered and evaporated to dryness to give a yellow solid which was loaded on to a 12+M Biotage silica column and eluted with cyclohexane:ethyl acetate (3:1 to 1:2). Product-containing fractions were evaporated to dryness to give a solid (39 mg). LCMS (Method C): Rt=0.95, MH+=530
