Reaction Steps

A suspension of 7-(4-methoxypyridin-2-yl)-2-quinolone (130 mg) in phosphorus oxychloride (5 ml) was refluxed for 2 hours. The mixture was evaporated under reduced pressure. The residue was poured into a saturated aqueous sodium hydrogencarbonate solution and extracted with dichloromethane. The organic layer was washed with brine, dried over sodium sulfate and evaporated under reduced pressure to give 2-chloro-7-(4-methoxypyridin-2-yl)quinoline (140mg).
