Procedure

A mixture of (S)-2-(1-(2,8-dichloroquinolin-3-yl)ethyl)isoindoline-1,3-dione (0.2000 g, 0.5388 mmol), 2,3-difluorobenzeneboronic acid (0.09358 g, 0.5926 mmol), tetrakis(triphenylphosphine)palladium (0.03113 g, 0.02694 mmol), and sodium carbonate anhydrous (0.2855 g, 2.694 mmol) in acetonitrile-water (3:1) (5.200 mL, 0.5387 mmol) was stirred at 85° C. After 19 h, the mixture was cooled to room temperature and partitioned between CH2Cl2 (30 mL) and 2 N HCl (30 mL). The organic layer was washed with brine (50 mL×2), dried over Na2SO4, filtered, and concentrated under reduced pressure to give 2-(((S)-1-(8-chloro-2-(2,3-difluorophenyl)quinolin-3-yl)ethyl)carbamoyl)benzoic acid as a yellow foam type solid: LC-MS (ESI) m/z 467.0 [M+H]+.
