Procedure

A mixture of (S)-2-(1-(2,8-dichloroquinolin-3-yl)ethyl)isoindoline-1,3-dione (120.0 mg, 323 μmol), 2-chloro-5-fluoropyridin-3-ylboronic acid (57 mg, 323 μmol), tetrakis(triphenylphosphine)palladium (37 mg, 32 μmol), cesium fluoride (147 mg, 970 μmol) and copper(I) iodide (12 mg, 65 μmol) in 1,2-ethanediol, dimethyl ether (3.0 mL, 323 μmol) was subjected to microwave at 100° C. for 1 h, cooled to room temperature. Filtration of the resultant mixture and rinsed with EtOAc, the filtrates were collected and concentrated. Purification of the residue by flash chromatography over silica gel, gradient elution, 0-100% EtOAc in hexane, gave 2-((S)-1-(8-chloro-2-(2-chloro-5-fluoropyridin-3-yl)quinolin-3-yl)-ethyl)isoindoline-1,3-dione, Mass Spectrum (ESI) m/e=466.0 (M+1).
