Reaction Steps
To a solution of 3-bromo-4-fluoroaniline (10.00 g, 52.63 mmol) in 6N HCl (150 mL) was added (E)-but-2-enal (7.524 mL, 92.10 mmol) dropwise over 10 minutes at 106° C. The reaction was stirred at 106° C. for 2 hours. After cooling to ambient temperature, the reaction mixture was basified with ammonium hydroxide to about pH 12, extracted with DCM (2×100 mL), dried (sodium sulfate), filtered and concentrated under reduced pressure. The residue was purified by flash chromatography on silica gel (hexane/ethyl acetate 5:1) to give 7-bromo-6-fluoro-2-methylquinoline (3.26 g, 25.8%) as a solid.
