Versuchsvorschrift
A solution of 3-isobutyryl-8-(benzoyloxymethyl)-4(1H)-quinolone (11.81 g, 29.9 mmol) in phosphoryl chloride (100 ml) was heated at reflux for 2.5 hours, then the excess phosphoryl chloride evaporated. Water was added and the product extracted into a mixture of dichloromethane and isopropyl alcohol. Drying and evaporation of the organic layer gave crude 3-isobutyryl-4-chloro-8-(benzoyloxymethyl)quinoline (12.0 g), contaminated with isopropyl alcohol. This was used without further purification.
