Procedure

9-Hydroxyphenalenone (1.5 g) was placed in a 100 mL round-bottom flask. Dry toluene (50 mL) was added to the flask together with aluminum chloride (0.113 g). The solution turned yellow-orange, and a precipitate began to form. The mixture was refluxed at 110° C. overnight. The flask was then cooled and the contents filtered. Crude yield 1.69 g, mp>300° C.
