7-Fluoro-9,10-dihydro-9,10-dioxo-2-anthroic acid (15 g), phosphorus pentachloride (12 g) and xylene (300 ml) were heated for 15 minutes at 100°-130° till a clear solution was obtained. This was concentrated to small volume and allowed to crystallise. The product was washed with light petroleum (bp 40°-60°) to give 7-fluoro-9,10-dihydro-9,10-dioxo-2-anthroyl chloride (14 g).
