Reaction Steps
Prepared according to procedure F by stirring 2,4-dichloro-5,7-difluoro-3-methylquinoline (550 mg, 2.22 mmol), 2-(methylthio)phenylboronic acid (484 mg, 2.88 mmol), sodium carbonate (705 mg, 6.65 mmol), Pd(PPh3)4 (128 mg, 0.11 mmol), acetonitrile (5.2 mL), and water (1.3 mL) at 100° C. in a microwave reactor for 1 h. Purification by column chromatography (silica gel, 0-20% EtOAc in hexanes) gave 4-chloro-5,7-difluoro-3-methyl-2-(2-(methylthio)phenyl)quinoline as a white amorphous solid. Mass Spectrum (ESI) m/e=336.1 (M+1).
