Vorschrift

1.65 g (10 mmol) N-butyl-2-aminoaniline and 0.84 g (5 mmol) 2,5-dimethoxybenzoquinone i 50 ml glacial acetic acid are heated to boiling under reflux for three hours followed by evaporation to dryness. The darkblue powder is treated with 50 ml 10% ammonia solution and washed thoroughly with water, ethanol, and acetone (10 ml). After a thorough drying under vacuum, 1.95 g (95%) 5,12-dibutyl-5,12-dihydro-5,7,12,14-tetraazapentacene is obtained.
