Participants

Reaction Steps

Chloranil (0.054 g, 0.22 mmol) was added to a solution of dimethyl 5,14-dihydro-1,4,6,8,9,10,11,13-octapropylpentacene-2,3-dicarboxylate (0.147 g, 0.2 mmol) obtained in REFERENCE EXAMPLE 6 in benzene (5 ml). The mixture was then refluxed for 24 hours. After concentration, chloroform was added to the residue followed by filtration. After concentration, the concentrate was recrystallized from benzene to give 0.048 g of the title compound as a blue solid. The isolation yield was 33%.
