Reaction Steps

The 2,4-dichloro-5,7-difluoro-3-methylquinoline (300 mg, 1.20 mmol) and 1-methylpiperazine (140 μL, 1.20 mmol) were slurried in isopropanol (2.4 mL) and heated in a microwave reactor at 100° C. for 6 h. The reaction was cooled to rt and the resulting plug was slurried in EtOAc and filtered to give 4-chloro-5,7-difluoro-3-methyl-2-(4-methylpiperazin-1-yl)quinoline. Mass Spectrum (ESI) m/e=312.1 (M+1).
