40 g (94 mmol) of 6-anthracen-9-ylphenanthrene-9-carboxylic acid are suspended in 250 ml of quinoline, the suspension is saturated with N2, 11.8 g (38 mmol) of copper chromite are added, and the mixture is heated at the boil for eight hours. The mixture is subsequently poured into 1 l of MeOH/water, and the black solid is filtered off with suction, washed with MeOH and subjected to Soxhlet extraction with CHCl3. Removal of the solvent leaves a greyish solid, which is recrystallised twice from dioxane. The yield is 30.6 g (92%).
