5,12-Dihydro-1,2,3,4,6,11-hexapropylnaphthacene (0.503 g, 1.04 mmol), 2,3-dichloro-5,6-dicyanobenzoquinone (0.260 g, 1.14 mmol) and 1,4-dioxane (3 ml) were charged in a reactor. The mixture was refluxed for 24 hours. After cooling, the precipitates were removed by filtration. The solvent in the mixture was removed in vacuum followed by recrystallization from chloroform/methanol. The orange red title compound (0.112 g) was obtained. The NMR yield was 36% and the isolation yield was 22%.
