Acetic Acid → HCID 20159007, compound

Participants

Reaction Steps

A mixture of 6-(3-pyridyl)-2-(1H)-quinolone monohydrochloride (0.50 g), bromine (3.2 g), acetic acid (10 cm3) and triethylamine (0.195 g) was heated under reflux for 24 hours and then cooled. Ether (20 cm3) was then added to the cooled reaction mixture and the resulting yellow solid was filtered off. This material was purified by preparative layer chromatography eluting with chloroform:methanol, 15:1 (4 elutions), to afford 3-bromo-6-(3-pyridyl)-2-(1H)-quinolone, m.p. 297°-300°, (0.11 g).
