Reaction Steps

3-Butyryl-6-methoxy-4(1H)-quinolone (20 g) was heated under reflux in phosphorus oxychloride for 1 hour. The mixture was cooled, poured onto ice and carefully neutralized with ammonia solution. The mixture was extracted with dichloromethane and the combined extracts washed with sodium hydrogen carbonate solution (×2) and brine. The organic solution was dried, filtered and evaporated to give 3-butyryl-4-chloro-6-methoxy-quinoline (13.3 g, 62%) as an oil which crystallized from ether/petrol; m.p. 73°-75°.
